A. Find the length of one side of a square with a 25 cm diagonal.
Solution:
use pythagorean theorem
since the given is a square, then
25² = x² + x²
625 = 2x²
x² = 625/2
x = √312.5
x = 17.68 cm
B. Find the length of the diagonal of a square with a 15 cm side.
Solution:
use pythagorean theorem
since the given is a square, then
d² = 15² + 15²
d² = 225 + 225
d² = 450
d = √450
d = 21.21 cm
