Answer 2

GivEn:

• Perimeter of regular pentagon = 245cm

To finD:

• One side of this pentagon.

Solution:

Here, we are given that perimeter of pentagon is 245cm.

We know that pentagon is a polygon with 5 sides and 5 angles.

Formula of perimeter:

Perimeter of pentagon = 5s ( where s is the side of pentagon)

Putting values in formula:

Perimeter of pentagon = 5s

=> 245 = 5s

=> s = 245/5

=> s = 49

Therefore,

Side of pentagon is 49cm
