A regular polygon has ten (10) equal sides ( since it is regular). We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a Solving for a (the side measurement), we have: 100 = 10a a= 100/10 a =10
We can now proceed in solving the area and the formula is shown below: Area = 5/2 a√ (5+2√5) Area = 5/2 * 10√(5+2√5) Area = 76.94 square units
