Answer:
We know that all the sides of a square are equal.
Perimeter of a Square
Perimeter of the square ABCD
= AB + BC + CD + AD
= 2 cm + 2 cm + 2 cm + 2 cm
= (2 × 4) cm
= 8 cm
Perimeter of a square is 4 times of s side.
Perimeter of a square = 4 × length of a side.
Let us consider some of the examples on perimeter of a square:
Examples on Perimeter of a Square
1. Each side of a square is 2.5 cm. Find its perimeter.
Solution:
Side = 2.5 cm
Therefore, perimeter of a square = 4 × length of a side
= (4 × 2.5) cm
= 10 cm
2. A rope of length 96 m was used to fence a square garden. What is the length of the side of the garden?
Solution:
Perimeter of the garden = Length of the rope = 96 m
We know that perimeter of a square = 4 × length of a side
So, 4 × length of a side = 96 m
Length of a side = 964 m = 24 m
Therefore, length of the one side of the square shape garden is 24 m.
3. Find the perimeter of a square shaped playground whose each side length 12 m.
Solution:
We know a square has four equal sides. So, we can easily calculate the perimeter of a square.
The formula for finding the perimeter of a square is:
P = 4 × length of a side
= 4 × 12 m
= 48 m
