WebTo calculate the area of a polygon with the help of apothem, we use the formula: a a = apothem. P P = perimeter. Example: Find the area of a regular hexagon, if the side length is 5 5 inches, and the apothem is 3 3 inches. P = [side length]×[no. of sides] = 5 ×6 = 30 P = [ side length] × [ no. of sides] = 5 × 6 = 30. WebRadius is the distance from the center to a corner. it is also important to know the apothem This works for any regular polygon. Choose a side and form a triangle with the two radii that are at either corner of said side. You know both radii are 8 cm, which means you have an isosceles triangle.
