A polygon is a two-dimensional (2-D) closed figure made up of straight line segments. In geometry, hexagon is a polygon with 6 sides. If the lengths of all the sides and the measurement of all the angles are equal, such hexagon is called a regular hexagon.

Formulae used
a = side of hexagon
Perimeter of an Hexagon = 6a
Area of an Hexagon = \[ \frac{3 \sqrt[]{3}}{2} \times a^2 \]
