Question

A square has a perimeter of 39.6 millimeters. What is the length of each side?​

Answer 1

9.9 millimeters

Explanation:

To find the perimeter of a square,

Equation: 4 • length = P

So in this case, we're just working backwards. To find the length, divide.

39.6/4 = 9.9

Answer 2

9.9 mm

Explanation:

let
`x` = length of one edge of the square

perimeter of a square = 4
`x`

⇒ 39.6 = 4
`x`

⇒
`x` = 39.6 ÷ 4 = 9.9 mm
