Question

Calculate the perimeter of a rectangular carpet 13.5 long and 9 wide

Answer 1

Answer:

Cost of covering room floor =Rs60 per metre.

Length of room =16m

Breadth of room =13.5m

Breadth of carpet =75cm=0.75m

=16×13.5

=216

⇒ Area of room is 216m

Length of carpet can be calculated by using below formula:

Length of carpet =

(Breadth of carpet)

(area of0.75

216 =288m

Now,

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