# Perimeter of regular pentagon

Perimeter is the sum of all the sides of a closed figure
A regular pentagon is a five-sided polygon.
All the five sides of regular pentagon are equal.
Perimeter of Regular Pentagon is equal to five times the length its side.
Perimeter of Regular Pentagon = 5 x Length of each side

Question 1

Find the perimeter of a regular pentagon of side 3cm ?

Explanation

A regular pentagon is a five-sided polygon.
All the five sides of regular pentagon are equal.
So, Length of each side of regular pentagon = 3cm
Perimeter of regular pentagon = ( 5 x Length of each side ) units
= ( 5 x 3 ) cm
= 15 cm

Question 2

Find the perimeter of a regular pentagon of side 16cm ?

Explanation

A regular pentagon is a five-sided polygon.
All the five sides of regular pentagon are equal.
So, Length of each side of regular pentagon = 16cm
Perimeter of regular pentagon = ( 5 x Length of each side ) units
= ( 5 x 16 ) cm
= 80 cm

Question 3

Find the perimeter of a regular pentagon of side 25cm ?

Explanation

A regular pentagon is a five-sided polygon.
All the five sides of regular pentagon are equal.
So, Length of each side of regular pentagon = 25cm
Perimeter of a regular pentagon = ( 5 x Length of each side ) units
= ( 5 x 25 ) cm
= 125 cm

Question 4

Find the perimeter of a regular pentagon of side 4.5cm ?

Explanation

A regular pentagon is a five-sided polygon.
All the five sides of regular pentagon are equal.
So, Length of each side of regular pentagon = 4.5cm
Perimeter of a regular pentagon = ( 5 x Length of each side ) units
= ( 5 x 4.5 ) cm
= 22.5 cm

Question 5

Find the perimeter of a regular pentagon of side 7.5cm ?

Explanation

A regular pentagon is a five-sided polygon.
All the five sides of regular pentagon are equal.
So, Length of each side of regular pentagon = 7.5cm
Perimeter of a regular pentagon = ( 5 x Length of each side ) units
= ( 5 x 7.5 ) cm
= 37.5 cm
