Question

The formula for the area of a regular polygon is mc003-1.jpg. What is the equation solved for a?

Answer 1

Just took the quiz.

The answer is a=2A/p

Answer 2

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 = (a*p)/2
A*2 = a*p
(2A)/p = a or a = (2*A) / p
