What will be the perimeter of a 12-sided regular figure of side 12.2 m ?

Answer

To find the perimeter of a 12-sided regular figure (also known as a dodecagon) with each side measuring 12.2 meters, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number of sides (n)**:
The figure is a 12-sided polygon, so \( n = 12 \).

2. **Identify the length of each side (s)**:
Each side of the polygon is given as 12.2 meters, so \( s = 12.2 \, \text{m} \).

3. **Use the formula for the perimeter of a regular polygon**:
The perimeter \( P \) of a regular polygon can be calculated using the formula:
\[ P = n \times s \]

4. **Substitute the values into the formula**:
Now, substituting the values of \( n \) and \( s \) into the formula:
\[ P = 12 \times 12.2 \]

5. **Calculate the perimeter**:
Now, perform the multiplication:
\[ P = 12 \times 12.2 = 146.4 \, \text{m} \]

6. **State the final answer**:
Therefore, the perimeter of the 12-sided regular figure is \( 146.4 \, \text{meters} \).

### Final Answer:
The perimeter of the 12-sided regular figure is **146.4 meters**.
