Question

Answer 1

The area of a square is the length of a side squared, so the length of the side is the square root of the area.

So the length of the side in this problem is square root (40000) = 200 feet.

The two sides of a square and the diagonal form a right triangle.

We use the Pythagorean Theorem to find the length of the diagonal = sqrt (200^2 + 200^2) = 282.84 feet.
