To calculate the perimeter of a regular octagon, you will want to use the formula for the perimeter of a polygon:
- Perimeter (P) = Number of sides (n) × Length of one side (s)
For a regular octagon:
- Number of sides (n) = 8
- Length of one side (s) = 8 cm
Now, plug the values into the formula:
- P = 8 × 8 cm
- P = 64 cm
Therefore, the perimeter of the regular octagon is 64 cm.
This simple method allows you to quickly find the perimeter for any regular octagon as long as you know the length of one side. Just remember that the beauty of a regular octagon is that all sides are of equal length, making your calculations straightforward!
