Hi everyone.

Pic related. The answer should be 500m^2. I don't know how to calculate this. Could someone explain the method?

Didn't bothering looking for an easier method.
Split BCD into two right angles then work out the area of both.

Use law of sines (http://www.sparknotes.com/testprep/books/sat2/math2c/chapter9section9.rhtml) to find angles and third edge.

Bisect into two right-triangles.

1/2*base*height.
