Calculate the area of a regular polygon using A = ½ns² × cot(π/n). Enter the number of sides and side length.
Calculate the area of a regular polygon using A = ½ns² × cot(π/n). Enter the number of sides and side length.
The number of equal sides of the polygon (minimum 3).
The length of each side of the polygon.
The area of a regular polygon equals one-half the number of sides times the side length squared times the cotangent of π divided by the number of sides.
