Question

7) The length of a room is two times of its breadth
and is 30 m. Find the area of the carpet so that
the whole floor can be carpeted.​

Answer 1

Answer:

450 m²

Step-by-step explanation:

Area =L × B

= 15m × 30m

Answer 2

The area of the carpet so that the whole floor can be carpeted is 450m^{2}450m

2

Step-by-step explanation:

Let the breadth of a room is x

Given Length of a room is two times its breadth

So length of a room is 2x

Given length of a room is 30m

so we have 2x=30 m=30m

or x =\frac{30}{2} m=

2

30

m

or x=15 m=15m

so Breadth of the room is 15m15m

and length of the room is 30m30m

We know area of the rectangle is length \times× breadth

so Area of the carpet is 15m\times30m15m×30m

=450m^{2}=450m

2

so area of the carpet so that whole floor can be carpeted is 450m^{2}450m
