Question

11.A hall is 50 m long and 22 m broad. Its floor is covered with 2.5 m broad matting. Find the length of the matting.​

Answer 1

Step-by-step explanation:

Cost of covering room floor =Rs60 per metre.

Length of room =16m

Breadth of room =13.5m

Breadth of carpet =75cm=0.75m

We know, Area of room =Length×Breadth

=16×13.5

=216

⇒ Area of room is 216m

2

Length of carpet can be calculated by using below formula:

Length of carpet =

(Breadth of carpet)

(area of room)

=

0.75

216

=288m

Now,

Cost of covering the floor =288m×Rs60 per meter =Rs17280
