A regular hexagon has a side length of 6 units.

The hexagon can be divided into six congruent and triangles.

The apothem is perpendicular to a side and forms two ° right triangles.

The apothem is 3√3 units because it is .

If the formula for the area of a polygon is

1/2(perimeter)(apothem), the area of the hexagon is √3 square units
