Perimeter of regular octagon is  ________ .

Options

A. `4 xx`  length of one side
B. `6 xx`  length of one side
C. `8 xx`  length of one side
D. `7 xx`  length of one side

Answer

To find the perimeter of a regular octagon, follow these steps:

### Step-by-Step Solution:

1. **Understand the Shape**: A regular octagon is an 8-sided polygon where all sides and angles are equal.

2. **Identify the Length of One Side**: Let the length of one side of the octagon be denoted as \( x \).

3. **Calculate the Perimeter**: The perimeter (P) of a polygon is the sum of the lengths of all its sides. Since a regular octagon has 8 equal sides, the perimeter can be calculated as:
\[ P = \text{Number of sides} \times \text{Length of one side} \]
For an octagon, this becomes:
\[ P = 8 \times x \]

4. **Final Expression**: Therefore, the perimeter of the regular octagon is:
\[ P = 8x \]
