Answer 1

Answer:

Pls mark me brainlist

Step-by-step explanation:

Given :

Length of the floor is 5m

The breadth of the floor is 4m

So, ( applying ar. l×b )

ar. of floor =4m×5m=20m

. 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 .

Answer 2

Answer:

Area of rectangle =LXB

=5X4

=20sq cm

Area of square = side X side

=3X3

=9sq cm

20-9

11 sq cm
