# Perimeter of Equilateral Triangle

Perimeter is the sum of all the sides of a closed figure.
An equilateral triangle is a triangle having all three sides equal in length.
Perimeter of equilateral triangle is equal to three times the length of a side of a triangle.
Perimeter of Equilateral Triangle = 3 x Length of each side

Question 1

Find the perimeter of an equilateral triangle of side 9 cm?

Explanation

An equilateral triangle is a triangle having all three sides equal in length.
Length of each side of an equilateral triangle = 9 cm
Perimeter of an equilateral triangle = ( 3 x Length of each side ) units
= ( 3 x 9 ) cm
= 27 cm

Question 2

Find the perimeter of an equilateral triangle of side 25 cm?

Explanation

An equilateral triangle is a triangle having all three sides equal in length.
Length of each side of an equilateral triangle = 25 cm
Perimeter of an equilateral triangle = ( 3 x Length of each side ) units
= ( 3 x 25 ) cm
= 75 cm

Question 3

Find the perimeter of an equilateral triangle of side 16 cm?

Explanation

An equilateral triangle is a triangle having all three sides equal in length.
Length of each side of an equilateral triangle = 16 cm
Perimeter of an equilateral triangle = ( 3 x Length of each side ) units
= ( 3 x 16 ) cm
= 48 cm

Question 4

Find the perimeter of an equilateral triangle of side 4.5 cm?

Explanation

An equilateral triangle is a triangle having all three sides equal in length.
Length of each side of an equilateral triangle = 4.5 cm
Perimeter of an equilateral triangle = ( 3 x Length of each side ) units
= ( 3 x 4.5 ) cm
= 13.5 cm

Question 5

Find the perimeter of an equilateral triangle of side 7.5 cm?

Explanation

An equilateral triangle is a triangle having all three sides equal in length.
Length of each side of an equilateral triangle = 7.5 cm
Perimeter of an equilateral triangle = ( 3 x Length of each side ) units
= ( 3 x 7.5 ) cm
= 22.5 cm
