## Hexagon

A hexagon is a polygon with six sides. The sum of the internal angles totals 720°. In a regular hexagon, each individual angle measures 120°.

### Area
The formula for the area of a regular hexagon with side length `s` is:

<code>A = (3√3*s<sup>2</sup>)/ 2</code>

For a hexagon with a side length of 4, the area would be calculated as:

<code> (3√3*<b>4</b><sup>2</sup>)/ 2 ≈ 41.57</code>

### Examples
A natural example of a hexagonal grid are bees' honeycombs.

An unnatural example of a hexagonal grid is the New York County Supreme Court building on Foley Square, Manhattan:
