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.
How to find the perimeter of a square
In finding the perimeter of a square make sure all units of measurement are the same. Using the figure below which is a square the perimeter of the square is been found by adding the distance of its edges.
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
