This **Perimeter of a Polygon** calculator computes the perimeter of a regular polygon (**P**) based on the number of sides (**n**) and the length of the sides (**s**)

**INSTRUCTIONS:** Choose units and enter the following:

- (
**n**) - This is the number of sides of the regular polygon - (
**s**) - This length of a side

**Polygon Perimeter (P):** The calculator returns the perimeter in meters. However, this can be automatically converted to other area units via the pull-down menu.

- Area of a Polygon based on the length and number of sides.
- Area of a Polygon based on the number of sides and the outer radius.
- Area of a Polygon based on the number of sides and the inner radius.
- Perimeter of a Polygon based on the number and length of sides.
- Perimeter of a Polygon based on the number of sides and the outer radius.
- Perimeter of a Polygon based on the number of sides and the inner radius.
- Length of a Polygon Side based on Circumscribed Circle Radius
- Length of a Polygon Side based on Inscribed Circle Radius

The formula for the perimeter of a polygon based on the number and length of sides is:

P = n • s

where:

- P is the perimeter of a polygon
- s is the length of a side
- n is the number of sides
