Question

A rectangular floor of a room is 18 m long 12 m wide.Find the cost of covering the floor with carpet 6 m wide at Rs 40 per metre.

hintHint:

Area of a rectangle = length × breadth

The correct answer is: ∴ Cost of covering the floor with carpet is Rs. 1,440.


    Step-by-step solution:-
    As per the given information-
    Floor is to be fully covered with the carpet.
    ∴ Area of the carpet = Area of the floor …...................................................................... (Equation i)
    Now, For the floor-
    Length = 18m
    Breadth = 12m
    ∴  Area of the floor = length × breadth
    ∴  Area of the floor = 18 × 12
    ∴  Area of the floor = 216 m2 ....................................................................................... (Equation ii)
    From Equations i & ii-
     Area of the carpet = 216 m2
    ∴  length × breadth = 216
    ∴ length × 6 = 216 ..................................................................................................... (From given information)
    ∴  length = 216 / 6
    ∴  length = 36 m
    Cost of carpet @ Rs. 40 per mt = 36 m × Rs. 40 per mt
    ∴ Cost of carpet @ Rs. 40 per mt = Rs. 1,440
    Final Answer:-
    ∴ Cost of covering the floor with carpet is Rs. 1,440.
