i hope this helps.
For any regular polygon, the area can be expressed in terms of its apothem
and its perimeter
like this:
For the problem the apothem
So we need to find the perimeter. A regular hexagon is built up by equilateral triangles, so the radius is equal to each side, therefore the perimeter is given by:
Finally, if we substitute in the first equation:
