The number of degrees in a polygon is given by the equation (n-2)*180 where n is the number of sides. The number of degrees in a hexagon is 4*180=720. Since it is a regular hexagon, each angle is equal. 720/6=120° per angle.

The hexagon can be split into six equal equilateral triangles whose sides are 6. The height of each triangle is √3/2*s or 3√3. The area of each triangle, then, is 1/2*6*3√3 = 9√3. Multiply by 6 to get the area of the hexagon: 54√3
