How to find the area of a polygon formula?

Understand the Problem

The question is asking for the formula to calculate the area of a polygon, which typically involves understanding the specific type of polygon and the method of calculation required for it, such as using the coordinates of its vertices or specific formulas for regular polygons.

Answer

area = (1/2) x perimeter x apothem

The area of a regular polygon is found using the formula: area = (1/2) x perimeter x apothem.

Answer for screen readers

The area of a regular polygon is found using the formula: area = (1/2) x perimeter x apothem.

More Information

This formula works specifically for regular polygons. For irregular polygons, methods like triangulation or coordinate geometry may be used.

Tips

Common mistakes include confusing the apothem with the radius or using incorrect side lengths to calculate the perimeter. Always ensure the correct measurements are used.
