What is Meant by Perimeter of a Square?
In mathematics, a square is defined as a closed two-dimensional figure with four sides. The important property of square is that all the sides of the square are of equal measure and each interior angles of a square form a right angle. Since the square has four sides, the polygon is considered as a quadrilateral and the sum of interior angles of a square is equal to 360 degrees. The perimeter of a square is defined as the total length of all sides of a square. Therefore, the square perimeter can be found by adding all the sides of a square. If “a” is the side of a square, then the formula to calculate the perimeter of a square is given by
The perimeter of a Square, P = a+a+a+a units
Perimeter = 4a units.
Solved Example on Perimeter of a Square
Example 1:
Determine the perimeter of a square whose side length is 3 cm
Solution:
Given that,
Side length, a = 3 cm
We know that the formula to calculate the perimeter of a square is 4a units.
Now, substitute the value of “a” in the formula, we get
The perimeter of a square = 4 (3)
P = 12 units
Therefore, the perimeter of a square is 12 units.
Example 2:
If the area of a square is 25 cm2, then determine the perimeter of a square.
Solution:
Given that, the area of a square is 25 cm2.
From the area, we can find the value of a.
We know that the area of a square = a2 units
Therefore, a2 = 25
Now, take the square root, we get the value of “a”.
It means that, a =√25 = 5 cm
Hence, the value of a is 5 cm.
Now, substitute the value of a = 5 in the perimeter formula
The perimeter of a square = 4(5) = 20 units
Hence, the square perimeter is 20 units.
