How to find the perimeter of a square, formula | example

The perimeter of a square is the total distance or length of all squares sides of the square. A square is a special rectangle with all sides equal. The diagonals of squares bisect or cut each other at right angles (90°). A square has four lines of symmetry and the diagonals also bisect the opposite angles. On this page, we will discuss the perimeter of a square in detail.

What is a Perimeter of a square?

the perimeter of a square is the total distance around the square. To find the perimeter of a square we add the distance of the sides of the square since all four sides of a square are equal, then the formula for finding the perimeter of a square = 4 × L, where L = length of the square.

Let’s look at some examples of a perimeter of a square.

Example 1. Find the perimeter of a square with sides of 7cm.

Solution

perimeter of a square = 4L, where L= length = 7cm

= 4 × 7cm

= 28 cm

Example 2. A square has a side of 200cm. Find the perimeter of the square in meters (m).

solution

first change the 200cm to m

i.e 200cm = 2m

Note that every 100 cm =1m

the perimeter of a square = 4 × length of one side

= 4 × 2m

= 8m
