The perimeter of the regular pentagon is 10 centimeters.
Given that the area of the regular pentagon is 6.9 cm2, and a regular pentagon has an apothem with length 1.38 centimeters and an area of 6.9 centimeters squared, to determine what is the perimeter the following calculation must be performed:
- (Perimeter x apothem) / 2 = Area
- 1.38X / 2 = 6.9
- 1.38X = 13.80
- X = 13.80 / 1.38
- X = 10
Therefore, the perimeter of the regular pentagon is 10 centimeters.
