# Find the perimeter of a regular octagon if one side has a measure of 8 cm.

A regular octagon is a polygon with eight congruent sides. The perimeter of a polygon is the sum of all its sides.

## Answer: The perimeter of a regular octagon with side 8 cm is 64 cm.

Let's find the perimeter.

**Explanation:**

Given: Side length = 8 cm

The perimeter of a regular polygon can be calculated by multiplying the number of sides with the length of each side.

⇒ Perimeter = 8 × 8 cm [An octagon has 8 sides]

⇒ Perimeter = 64 cm.

We can calculate the perimeter using perimeter calculator.
