Answer 1

Given,

The perimeter of regular pentagon = 20.5 cm

To find,

The length of it's side.

Solution,

We can easily solve this mathematical problem by using the following mathematical process.

Now, we know that, the regular pentagon has equal five sides.

So, the Length of one side = 20.5/5 = 4.1 cm

(This method is applicable for a regular pentagon only.)

Hence, the length of it's side will be 4.1 cm.
