Question

Find the area of the square.

Answer 1

Answer is provided in the image attached.

Answer 2

diagonal of a square = sqrt(2) times S ( side )

half the diagonal = 6 yards so the full diagonal would be 12 yards

so you get

12 = sqrt(2) * S

S = 12/sqrt(2) = 8.485 yards

area = S^2

8.485^2 = 71.995

round answer to 72 square yards
