You can always find the area from breaking it up into smaller shapes. For example, a hexagon is basically 2 trapezoids. Some formulas for different shapes. Trapezoid: height × (base1 + base2) / 2 Rectangle: length x width Parallelogram: height x base Triangle height x base / 2
The area of a regular polygon is one-half the product of its apothem and its perimeter. Where a denotes the length of an apothem, and p denotes the perimeter.
