- n = number of sides
- s = length of one side
- a = apothem (the line drawn from the center of any polygon to the midpoint of one of the sides)
From inspection of the diagram:
Substitute the values into the formula and solve for A:



Therefore, the area of the given regular pentagon IJKLM is 60 in².
