Given:-

• Perimeter of regular octagon is 72 m.

To find:-

• Measure of one side.

Solution:-

We know that,

◆ Perimeter of octagon = 8a

In which,

• a is side of octagon.

➢ Perimeter of regular octagon = 72 cm.

So, Put perimeter of regular octagon in formula

➝ 8a = 72

➝ a = 72/8

➝ a = 9 m

A is side = 9 m

Therefore,

One side measure of regular octagon will be 9 m.

ATQ

The perimeter of a regular octagon is 72m.

Let the one side of a regular octagon is x.

perimeter of a regular octagon= 8×(side)

72= 8×x= 8x ....divide 72 by 8

72/8=x

9=x

Answer= 9
