Area of a regular polygon

Online calculator provides the opportunity to calculate the area of a regular polygon, where all sides and angles are equal. To do this, you need to enter the number of sides of the polygon n and the length of one of its sides a.

Area = (n * a^2) / (4 * tan(pi/n)),
where:
n - number of sides of the polygon,
a - length of one of the sides of the polygon.

This formula applies to regular polygons, where all sides and angles are equal. Just enter the number of sides n and the length of one of its sides a in the calculator, and it will automatically perform the calculation and return the area of the regular polygon.
