Answer 2

Answer :

Given :

An regular pentagon of side 3 cm

Required to find :

1. Perimeter of the pentagon

Solution :

What is a pentagon ?

• A geometrical figure which is made up of 5 line segments .
• A pentagon can be divided into 5 triangles
• If all 5 sides are equal then it is called as regular pentagon
• If all sides are of different lengths then it is called as irregular pentagon.

What is perimeter ?

In simple terms,

The length of the boundary is called as the perimeter

• But more preside definition is sum of the lengths of all it's sides will give us the perimeter.

Now , let's solve this question;

To solve we can use a formula

The formula is ;

Perimeter of the regular pentagon = 5 x side

So, using this formula let's solve the question

Side = 5cm

Perimeter of the regular pentagon = ?

=> 5 × side

=> 5 × 3

=> 15 cm.

Therefore;

Perimeter of the pentagon = 15cm
