Answer 3

Hey @SolomonZelman could help you out

Answer 4

What do you mean?

Answer 5

so the angle is bisected when you create the diagonal right?
so then use that angle which is 45 degrees to find th side of the triangle
so use sin45 = x/20

Answer 6

solve for x

Answer 7

so 20sin45 = x

Answer 8

x = 14.14
that is one side of the square
so to find area
x * x = area of square
= 199.93
