For a regular hexagon with side length (s): (A = frac{3sqrt{3}}{2}s^2)
If the apothem (a) and perimeter (P) are known: (A = frac{1}{2}Pa)
If the circumradius (R) is known for a regular hexagon: (A = frac{3sqrt{3}}{2}R^2)
If the hexagon is irregular, divide it into triangles, find each triangle’s area, and add them
If coordinates of the vertices are known, use the polygon area formula (shoelace formula)
