Area of a Hexagon

A hexagon is a 6-sided, 2-dimensional geometric figure. The total of the internal angles of any hexagon is 720°. A regular hexagon has 6 rotational symmetries and 6 reflection symmetries. All internal angles are 120 degrees.

Examples :

Input: 4
Output: 41.5692

Input: 6
Output: 93.5307

Number of vertices: 6
Number of edges: 6
Internal angle: 120°
Area = (3 √3(n)2 ) / 2



How does the formula work? There are mainly 6 equilateral triangles of side n and area of an equilateral triangle is (sqrt(3)/4) * n * n. Since in hexagon, there are total 6 equilateral triangles with side n, are of the hexagon becomes (3*sqrt(3)/2) * n * n
