Perimeter = All of the lengths of he sides added up
Pentagon has 5 sides
60/5 = 12
You add the five lengths.

The formula for the perimeter of ANY regular pentagon isPerimeter = 5 x (length of one side)
Area = 110.11 cm2
"Penta" = 5 so 75/5 cm
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.

The formula for the perimeter of ANY regular pentagon isPerimeter = 5 x (length of one side)
Providing that it is a regular 5 sided pentagon then the perimeter is 5*921.6 = 4608 feet
Area = 110.11 cm2
regular pentagon has five sides,perimeter=140*5=700cm
"Penta" = 5 so 75/5 cm
To find the perimeter of a regular pentagon with 9cm sides, you would multiply the length of one side by the total number of sides. In this case, 9cm x 5 sides = 45cm. Therefore, the perimeter of a regular pentagon with 9cm sides is 45cm.
The boy had to find the area and perimeter of the pentagon.
