Question

What’s the area of a square with a diagonal of 8in

Answer 1

Because the diagonal of a square is equal to length of one of the sides of the square, the lengths of each side are 8 inches.

Since area of a square is one side squared, we have

8^2 = 64.

So, the area is 64 inches^2

Answer 2

64 I think if not, then I'm sorry.
