Question

14. The perimeter of a church window is 80 inches. If the window is in the shape of a square, what is the length of each side of the window?

Answer 1

perimeter of a square is P = 4s...where s is the length of 1 side.

P = 4s
P = 80

80 = 4s....divide both sides by 4
80/4 = s
20 = s....so each side is 20 inches
