Question

If measure of regular octagon is 6 CM then its perimeter is *

48 CM

36 cm

54cm

56 cm

​

Answer 1

Given:

A regular octagon with

• Length (Measure) = 6 cm

What To Find:

We have to find the perimeter of the octagon.

Solution:

• Method 1.

To find the perimeter,

⇒ Sum of sides = Perimeter

Substitute the values,

⇒ 6 cm + 6 cm + 6cm + 6 cm + 6 cm + 6 cm + 6cm + 6 cm  = Perimeter

Add the sides,

⇒ 48 cm = Perimeter

• Method 2.

To find the perimeter,

⇒ 8 × Measure of side = Perimeter

Substitute the values,

⇒ 8 × 6 cm = Perimeter

Multiply the numbers,

⇒ 48 cm = Perimeter

∴ Thus, the perimeter is 48 cm.
