Go on solve it then you stupid fuck
Numbers on the drawing are inconsistent. The altitude should be sqrt(60), not 5.
(12 + 16) * 5 / 2 = 70
if you think common core is bad, you guys obviously don't remember new math which created a crater of arithmetic understanding

>>78880082
I don't get what's wrong with the problem?
You can solve it as a trapezoid or by two triangles+a square
What's so bad about it?
>>78880263
>>78880355
it's impossible to answer
>>78880082
5x12=60
5x16=80
80-60=20
20รท2=10
60+10=70
What is the problem here? Are todays kids retarded?
>>78880082
the triangle to the left is 8-5-2, an impossible triangle. So the whole thing turns out wrong
whats the problem?
the trapezoid consists of a 12x5 square, plus two triangles. the triangles together form a 5x4 square, so the total area is (12+4)*5 = 48*5 = 196.

>>78880681
Solve it both ways. You will get two different answers. This is because with the given height and lengths, the hypotwnuses of the two triangles that make up the sides of the trapezoid should not be 8
>>78880886
Ok while your kid is arguing with the teacher about how the triangle is impossible my kid will be sitting there waiting for him to catch up.
Who cares if it is impossible or "that isnt how it works". Its asking for a number, not a smart comment.
>>78881018
Depends how you do it faggotfuck
>>78880734
> 5 steps to resolve this problem
> does not see that the sides can't be 8
This problem can be done in 3 steps, by treating the shape as a modified rectangle
16+12=28
28/2=14
14*5=70
Also (16-12) / 2 = 2 and 5^2 + 2^2 =/= 8^2

>>78880886
And also, the kid should do it both ways, write down how he got his answer, then also note on the test that the triangle is an impossibility and explain why.

>>78881267
You chopped Panama in half, remember?
>>78881121
Youre a fucking idiot. Because of the fact that the shape is impossible, you can get two different answers depending on what method you use to solve for the area. I dont think your kid will be waiting for anything considering his dad taught him to blindly work instead of learning the basic concepts that make up geometry or any form of math or science by thinking critically and asking questions when things dont seem to add up. You are part of the problem.
>>78881194
That is cheating. It's heavily implied that the entire base is length 16.

>>78880914
>whats the problem?
First what is object A?
Next is the line 5 at 90 degrees to either line 12 or 16?
Are 12 and 16 parallel?
If the implication is that it's a 5x12 square with 8x5x2 triangles those triangles are mathematically impossible.
>>78881358
They are asking for a solution not a complaint. You are someone who quits when the odds arent in your favor huh? Just sit there and complain about how life is unfair and impossible?
>>78881194
Why do you assume that this is a right triangle? We don't know if it's right or not.
>>78880082
Area = h(B1+B2)/2
= 5(12+16)/2
=5(28)/2
=70

>>78881121
Jesus Christ you really are classic south hick, I went to school with people like you. If the question is wrong it shouldn't be counted. You can't arrive at a correct answer with an impossible question.
If the teacher marked your kid wrong, what would you do? Probably open another fosters and let it happen, useless parent.
>>78880082
Besides the fact the depicted shape is not possible, the questions is quite simpl. The area is 70
>>78881532
Not the same anon, but you can't correctly arrive at a solution you retarded hick. Get that through your thick skull.
>>78880725
>>78881018
>>78880263
It's 70 assuming its a trapezoid. where the hell you got i from is beyond me

I took the entire base as length 16 you fucking moron
>>78881541
>not getting the joke
If you want the real answer, here you go:
There are infinity possible solutions. The lower limit approaches A=sqrt(1008)=31.749015733 from above. The upper limit is A=40+sqrt[((20+sqrt(25+(16-sqrt39)^2))/2)(((20+sqrt(25+(16-sqrt39)^2))/2)-(sqrt(25+(16-sqrt39)^2)))(((20+sqrt(25+(16-sqrt39)^2))/2)-12)(((20+sqrt(25+(16-sqrt39)^2))/2)-8)]=82.684891941.
>>78881659
Hey you may not like my answer but it asked and I gave it a solution. You are welcome to complain and get caught up on a small detail but I could care less about textbook problems that have little to do with real life. Yeah I know the 2-3-5 rule, but this triangle is fucked so it gets a fucked up answer. Keep moving because it doesnt matter.
>>78880263
The fact that it's impossible for the sides to both be 8 and for the perpendicular height to be 5, given the width of both top and bottom.
>>78881194
>Implying that portion is a right triangle
>Implying that the 12 side tilts upwards
>Implying this is anywhere near correct or even possible
>>78880082
A = 80

It's impossible because there are no right angles designated on the dotted line. You can't assume any of the lines are drawn to scale.

>>78880082
The only thing i find wrong with OP pic is thae fact that for the triangle base lenght to be consistent with the trapezoid base lenght, the triangle base would have to be 2. Well, that way the hipotenuse is larger then the 2 catetus combined.
But i don't think it deserves the amount of reposting this does. After all, it's still a valid exercise to 5th graders, and very few would notice this mistake.
reminder
>>78881462
Youre stupid dude. To find the area of a triangle find the area of a square and divide it by two. Each triangle has an area of 10
>>78882051
What is impossible about it? Are you a fucking retard?
You can use the pythagorean theorem to find the base of both triangles and then just find the area of a rectangle and add.
>>78881236
A triangle with sides 5, 2, and 8 is not possible.
>>78880558
80. You're forgetting the other side. 2(1/2B*H) + (B*H)
>>78880082
the area of the square in the middle is
5 * 12 = 60
there is two times the same triangle so its a square
5 * 4 = 20
60 + 20 = 80
>>78882840
Nevermind, sorry, I'm retarded.
did i do it right?
>>78882457
16-12 = 4
4 / 2 = 2
2^2 + 5^2 =/= 8^2
>>78882457
Do it then, fucktard.
A right triangle, or in fact no triangle can have those measurements. You can solve just the numbers, but it's not really possible.
>>78882424
>Youre stupid dude. To find the area of a triangle find the area of a square and divide it by two. Each triangle has an area of 10
I think you need to check your math, and look up the definition of a square while you are at it.
Then I suggest you try and find the unknown length of a triangle with a side of 5 and a hypotenuse of 8.

USA having Unisex bathrooms would be FUCKING GREAT for contrators building new bathrooms.
Then they would get to section off less space and we could use that space for more commerence.
I haven't done math beyond addition and subtraction for years and all this geometry is giving me anxiety.
>>78883095
Accepting 5 as the height contradicts the Pythagorean theorem.
2^2 + 5^2 != 8^2

Was it length times width divided by height? I have never used the math related stuff I learned back then. Maybe if I had gotten a good paying job in chemistry, things would be different but you get rusty on this shit with each passing year.
>>78883796
good thing the problem doesn't require the Pythagorean theorem to solve and isn't a treatise on pythagorean mathematics then
>>78880617
I remember when they tried to teach me that. My brain shut down and I just solved it the logical way.
>>78883963
The problem is also missing the right angle indicator which would imply that 5 is the height. By making the assumption it is the height, you are the one making the mistake. It's a problem that can't be solved.
>>78881194
The pythagorean identity will only work on right triangles. It cannot be implied that the central angle in that triangle is right because there isn't an indicator (e.g. the box) that says that the angle is right.
>>78882171
>>Implying this is anywhere near correct or even possible
I didn't imply that you stupid sliteye
>>78882457
But the triangle is not a right triangle.
You can't imply that the triangle is right unless there's an indicator that says it's right. The Pythagorean Identity only works on right triangles.
>>78884314
You don't need to do pythags. Just take the area of the triangle x 2 + the area of the square. No pythags necessary. You already know the base is 2.
>>78880355
Any answer the kids puts down is ok

They aren't right triangles, Euclid.
If they were, sqrt(2x2 + 5x5) would have to equal sqrt(8x8).
