How to Calculate the Perimeter of a Square

Step-by-Step Guide

1. 1

   Step 1: Recall the formula for the perimeter of a square.

   For a square of side length S, the perimeter is simply four times the side length:
   P=4s.
2. 2

   Step 2: Determine the length of one side

   Depending on the assignment, you may need to measure the side with a ruler, or look at other information on the page to determine the side length.
   
   Here are some examples of perimeter calculations:
   If your square has a side length of 4, then P = 4 * 4, or
   16.
   
   If your square has a side length of 6, its P = 4 * 6, or
   24.
