Question

A room is 16 m long and 13.5 m broad find the cost of covering its floor with 75 m wide carpet at Rs 60 per m

Answer 1

area of room = length * breadth=16*13.5 m sq.

width of carpet=0.75 m

length of carpet required = 16*13.5/0.75=288 m

cost= 15 *288=4320 rupees

Answer 2

Answer:

Cost of covering room floor = ₹60 per metre.

Length of room = 16 m

Breadth of room = 13.5 m

Breadth of carpet = 75 cm = 0.75 m

We know, Area of room = Length × Breadth

= 16 × 13.5

= 216

=> Area of room is 216 m^2

Length of carpet can be calculated by using below formula:

Length of carpet = (area of room)/(Breadth of carpet)

= 216/0.75

= 288 m

Now,

Cost of covering the floor = 288 m × ₹60 per meter = ₹17280
