A square had a perimeter of 38 inches. We want to know the length of each side.
MissTica

Answer: 9.5

Step-by-step explanation:

Since a sqaure has all 4 equal sides, you can divide the square by 4 since there are 4 sides and it will be equal.

38 ÷ 4 = 9.5

Therefore, the length of each side will be 9.5. Hope this helps!
