Q6 of 97 Page 780

A room is 16 m long and 13.5 m board. Find the cost of covering its floor with 75-m-wide carpet at RS. 60 per metre.

Given: Cost of covering = Rs 60 per metre.


Breadth of carpet = 75 cm = 0.75 m


Length of room = 16 m


Breadth of room = 13.5 m



We know that,


Area of room = Length × Breadth


= 16 m × 13.5 m


= 216 m2


Now,




= 288 m


Now,


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


= Rs 17280
