Answer 2

Given : Reema wants to fix a border to a square carpet whose each edge is 3 metres.

To find : The length of the border.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the length of the border)

In this case,

The length of the border = Perimeter of the square carpet

Now, we know that,

Perimeter of a square = 4 × edge

So,

The border of the square carpet :

= 4 × 3

= 12 metres

(This will be considered as the final result of the given mathematical problem.)

Hence, the length of the border is 12 metres.
