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
