The formula for the perimeter of ANY regular pentagon isPerimeter = 5 x (length of one side)
Perimeter = All of the lengths of he sides added upPentagon has 5 sides60/5 = 12
You add the five lengths.
Volume is Area of the Base times the Height of the Prism. To find the area of a Regular Pentagon, you use the formula (1/2)*Perimeter*Length of Apothem.
Area = 110.11 cm2
The formula for the perimeter of ANY regular pentagon isPerimeter = 5 x (length of one side)
The length of each of the outside walls of the Pentagon in Washington, D.C., is 921.6 feet. Find the perimeter of the outside walls of the Pentagon
Multiply the known length by 5, because the sides are all the same length on a regular pentagon and a pentagon has 5 sides.
A pentagon, which is a 5-sided figure, will have a perimeter equal to the sum of the lengths of all the sides. This will be true for any polygon; the perimeter of any polygon is the sum of the lengths of all the sides. If the pentagon is a regular pentagon, then the perimeter will be 5 times the length of one of the sides. For any regular polygon, the perimeter will be the length of one side times the number of sides in that polygon.

You add the five lengths.
Volume is Area of the Base times the Height of the Prism. To find the area of a Regular Pentagon, you use the formula (1/2)*Perimeter*Length of Apothem.
Providing that it is a regular 5 sided pentagon then the perimeter is 5*921.6 = 4608 feet
The perimeter is the sum of the sides of a polygon. So, to find the perimeter of a pentagon, you need only to add up the 5 side lengths. In the event the pentagon is regular (all equal sides and angles) then you can multiply the measure of the side by 5 to get the perimeter.
Area = 110.11 cm2
Length = (Perimeter - twice width) / 2
Perimeter = 8 x (length of one side)
