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
