Polygon Calculator

A polygon that has all sides equal and all interior angles equal. Here you can calculate the area and perimeter of Polygon.

Area of Polygon [Using length of a side]:[ ((side)²×N)/(4Tan(π/N)) ]

Area of Polygon [Using radius (circumradius)]:[ ½×R²×Sin(2π/N) ]

Area of Polygon [Using apothem (inradius)]: [ A²×N×Tan(π/N) ][ Apothem(A) = R×Cos(π/N)

Perimeter of Polygon:[ N×(side) ]
