1. The length of a room is 5.5 m and width is 3.75 m. Find the cost of paving the floor by slabs at the rate of Rs. 800 per square metre.
= (5.5 × 3.75)m2
= 20.625m2
∴ Cost of paying
= Rs. (800 × 20.625)
= Rs. 16500
Solution:
Area of the floor= (5.5 × 3.75)m2
= 20.625m2
∴ Cost of paying
= Rs. (800 × 20.625)
= Rs. 16500
