## 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:
A = (3√3*s2)/ 2
For a hexagon with a side length of 4, the area would be calculated as:
(3√3*42)/ 2 ≈ 41.57
### 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:
