An alternative method to find the area of a regular polygon only requires two known variables, the length of the side and the number of sides.

The alternative formula for determining the area of a polygon is defined as:
\(A\) \(=\) \(\dfrac{1}{4}\) \(\cdot\) \(n\) \(\cdot\) \(L^2\) \(\cdot\) \(\cot(\dfrac{\pi}{n})\)
\(A\): the area of the polygon
\(n\): the number of sides
\(L\): the length of any side
The SI unit of area is: \(square \text{ } meter\text{ }(m^2)\)

Find \(A\)

Use this calculator to determine the area of a polygon when the number of sides and the length of any side are given.
