Question

A floor is 5 m long and 4 m wide. A square carpet of sides 3 m on the floor. Find the area of the floor that is not carpeted?

Answer 1

Answer:

Length of floor = 5 m and breadth of floor = 4 m

Area of floor = length x breadth

= 5 m x 4 m = 20 m.sq

Now, Side of square carpet = 3 m

Area of square carpet = side x side = 3 x 3 = 9 m.sq

Step-by-step explanation:

please mark me brainliest

Answer 2

Answer:

Length of the floor is 5m

The breadth of the floor is 4m

So, ( applying ar. l×b )

ar. of floor =4m×5m=20m^2

Side of the carpet is 3m

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

area of carpet=3m×3m=9m^2

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

area which is not carpeted or( uncarpeted ) =20m^2 −9m^2

=11m^2

.

Hence, answer Is 11m^2
