The formula for the area of a regular polygon is mc003-1.jpg. What is the equation solved for a?
Area of a regular polygon is computed using this formula:
Area = (a p) / 2
a = length of the apothem
p = perimeter of the polygon
Using the above formula, we can derive the formula for a.
A = (ap)/2
A2 = ap
(2A)/p = a or a = (2*A) / p
