Answer:
To find the perimeter of a regular pentagon, you need to know the length of one side and the number of sides. In a regular pentagon, all sides have the same length and the shape has 5 sides.
Let's say the length of one side of the regular pentagon is 's'.
The formula for the perimeter of a regular pentagon is:
Perimeter = 5s
This is because a regular pentagon has 5 sides of equal length, so you can simply add the length of each side together 5 times.
Therefore, the perimeter of a regular pentagon with a side length 's' is 5s.
