Question

If the diagonal of a square is 11.3 meters, approximately what is the perimeter of the square?

Answer 1

If the diagonal of a square is 11.3 meters, then basing on Pythagorean theorem, the side of square could be calculated:

S = sqrt(diagonal^2/2) = sqrt(11.3^2/2) = 8 (m)

=> Approximately, the perimeter of square is calculated by:

P = side x 4 = 8 x 4 = 32 (m)

Hope this helps!
