A+=+%281%2F4%29s%5E2n%2Acot%28180%5Eo%2Fn%29,
where s = length of a side, and n = number of sides.

By definition, all sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:
A=S%5E2N%2F4tan%28%28pi%29%2FN%29
where S is the length of any side, N is the number of sides,
pi is approximately 3.142, and tan is the tangent function calculated in radians
