Question

The perimeter of the picture frame is 36cm. If the frame is square what is the length of each side?​

Answer 1

9 cm

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
