# Perimeter of regular octagon

Perimeter is the sum of all the sides of a closed figure
A regular octagon is an eight-sided polygon.
All eight sides of regular octagon are equal.
Perimeter of Regular Octagon is equal to eight times the length its side.
Perimeter of Regular Octagon = 8 x Length of each side

Question 1

Find the perimeter of a regular octagon of side 7cm ?

Explanation

A regular octagon is an eight-sided polygon.
All eight sides of regular octagon are equal.
So, Length of each side of regular octagon = 7cm
Perimeter of regular octagon = ( 8 x Length of each side ) units
= ( 8 x 7 ) cm
= 56 cm

Question 2

Find the perimeter of a regular octagon of side 15cm ?

Explanation

A regular octagon is an eight-sided polygon.
All eight sides of regular octagon are equal.
So, Length of each side of regular octagon =15cm
Perimeter of regular octagon = ( 8 x Length of each side ) units
= ( 8 x 15 ) cm
= 120 cm

Question 3

Find the perimeter of a regular octagon of side 25cm

Explanation

A regular octagon is an eight-sided polygon.
All eight sides of regular octagon are equal.
So, Length of each side of regular octagon =25cm
Perimeter of a regular octagon = ( 8 x Length of each side ) units
= ( 8 x 25 ) cm
= 200 cm

Question 4

Find the perimeter of a regular octagon of side 3.2cm

Explanation

A regular octagon is an eight-sided polygon.
All eight sides of regular octagon are equal.
So, Length of each side of regular octagon =3.2cm
Perimeter of a regular octagon = ( 8 x Length of each side ) units
= ( 8 x 3.2 ) cm
= 25.6 cm

Question 5

Find the perimeter of a regular octagon of side 5.7cm

Explanation

A regular octagon is an eight-sided polygon.
All eight sides of regular octagon are equal.
So, Length of each side of regular octagon =5.7cm
Perimeter of a regular octagon = ( 8 x Length of each side ) units
= ( 8 x 5.7 ) cm
= 45.6 cm
