What is the area of a regular pentagon with a side length of 9 millimeters an an apothem length of 6.2 millimeters?

The formula for finding the area of a regular pentagon is: A= 1/4*{sqrt[5(5+2sqrt(5)]}*a^2 where * means multiply, ^2 means 't the power of 2 or squared) You only need the length of the side. So the area of this pentagon is given by A= 1/4{sqrt[5(5+2sqrt(5)]}*.9^2 =1/4*(6.8819)*0.81 = 1.3936 sq mm.


What is Area of a regular pentagon with radius of 5.1 and side of 7.5?
