The Polygon Perimeter from Area and Number of Sides calculator computes the Perimeter of a polygon based on the polygon's area (A) and number of sides (n).
INSTRUCTIONS: Choose units and enter the following:
Perimeter of a Polygon (P): The calculator returns the perimeter in meters. However, this can be automatically converted to compatible units via the pull-down menu.
A regular n-sided polygon is a polygon with n equal length sides and is a polygon which has n equal angles at the n vertices of the polygon. This formula uses the polygon:
`A = (n * s) / (4 * tan(pi/n))` to solve for s. This is the length of a side corresponding with a polygon of n sides and an area of A. The circumference is simply stated as follows:
` "Polygon Circumference" = s * n`
