Answer:

18

Step-by-step explanation:

A square has 4 sides of equal length.

The perimeter of the square is the sum of the lengths of the sides of the square.

P = perimeter; a = length of 1 side

P = a + a + a + a

P = 4a

We are told the perimeter is 72 yd.

4a = 72 yd

Divide both sides by 4.

a = 72/4 yd

a = 18 yd

Answer: 18
