I just want to clarify that you forgot to divide (625√3) by two. The area of the triangle is (1/2)(625√3) .

Since the rectangle has two triangles, the area of the rectangle is 2(1/2)(625√3) = 1,082

Thanks.

In the explanation we calculate the area of the rectangle (the desired area) by multiplying its sides 25 and 25√3 .

This is also a possible approach. As you can see it yields the same result for the desired area, 625√3 sq ft.
