Hi /sci/,
This question is probably a bit amateur for this community, but for some reason I'm having a hard time finding the surface area for this shape. I'm digging out a garden plot and my sister gave me somewhat odd measurements to go off of. I've drawn them out.
I keep getting different answers depending on the technique I used. I think it's 948 square feet but I also got 870 square feet.

I don't need an exact answer or anything just a rough estimate so I can order enough top soil and so that I know I'm on the right track.
It kind of threw me for a loop considering I have no angles to work with aside from the one 90 degree fence line in the bottom right.

OK I'll bite. Draw a line from the bottom left corner to top right. This divides it into two triangles. One triangle is a right triangle so the base and height are easy to determine. The hypotenuse, which is the third side of the other triangle, can be found by pythagorean theorem. Thus you know the lengths of all three sides of the other triangle, and can find its area using, e.g.,Heron's formula.

~650 sq. ft. using an online calculator

Brilliant got 649.8 using heron's formula. Haven't used that in years. I was way overthinking it.
Thank you for saving me here /sci/. I would have over ordered.

Word of advice. You can get a rough estimate of any surface by printing it out and weighing it

Where's he gonna get 650 square feet of paper in one sheet? Retard.

What is scale?
Draw the diagonal and use:
