The perimeter of a regular pentagon is 100 cm. How long is its each side?

The perimeter of a regular pentagon is 100 cm. How long is its each side?

To find the length of each side of a regular pentagon when the perimeter is 100 cm, you can use the formula for the perimeter of a regular polygon:

Perimeter = Number of sides × Length of each side

In this case, you have a regular pentagon, which has 5 sides. So, you can set up the equation as:

100 cm = 5 × Length of each side

Now, solve for the length of each side:

Length of each side = 100 cm / 5 Length of each side = 20 cm

So, each side of the regular pentagon is 20 cm long.
