# The perimeter of a square is 126 in. What is the length of a square's side?

Mar 22, 2018

$P = 31.5$ $\text{in.}$

#### Explanation:

The $p e r i m e t e r$ of any polygon is the total length of all the sides added together. Since this is a square, we only have $4$ sides to worry about.

In this problem, we are already given the $p e r i m e t e r$. What we are trying to find is the length of each side.

Knowing that on a square, all sides being equal in length, we need only divide our value of the $p e r i m e t e r$ by $4$.

So we should get:

$126$ $\text{in}$$/ 4$

$\implies 31.5$ $\text{in.}$
