Answer:
9 cm
Step-by-step explanation:
In a square, there are 4 sides of equal length. And we know that the perimeter of a square is P=4s
let P represent the perimeter of the square and let s represent the length of one side of the square.
So, we can say 36=4s
Divide each side by 4 to isolate the variable
9=s
9 cm
