Question

A floor is 5m long and 4m wide. A square carpet of side 3m is laid on the floor. find the area of the floor that is not carpeted

Answer 1

Given :

Length of floor is 5m

Breadth of the floor is 4m

So, ( applying ar. l × b )

ar. of floor =4m×5m=20m2. Side of the carpet is 3m

So, (applying ar. of sq. = side × side (s) )

area of carpet=3m×3m=9m2.

To find the area of the floor that is not carpeted or (uncarpeted) we will (-) minus the ar. of floor from ar. of carpet

area which is not carpeted or( uncarpeted ) =20m2-9m2

=11m2.

Hence,the ans. Is 11m sq.

Answer 2

Given: A floor is 5m long and 4m wide. A square carpet of side 3m is laid on the floor.

To find: The area of the floor that is not carpeted.

Solution:

The area of the floor can be calculated as follows.

$floor = 5*4$

         $= 20 m^{2}$

Now, the area of the carpet can be calculated as follows.

$Carpet = 3^{2}$

            $= 9 m^{2}$

In order to find the area of the floor that does not have carpet on it, the area of the carpet calculated must be subtracted by the area of the floor.

$uncarpeted = 20 - 9$

                  $= 11 m^{2}$

Hence, the 11 m² of the area of the floor does not have carpet on it.

Therefore, the area of the floor that is not carpeted is 11 m².
