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 m^2.

Length of the room, L= 5.5m

Width of the room, W = 3.75m

Cost of paving per square meter, $$\text{Cost per m}^2 = \text{Rs.}\, 800$$​​

Concept Used:
The cost of paving the floor depends on the area of the room and the cost per square meter.

​$$\text{Area of the room} = L \times W$$​​

​$$\text{Total Cost} = \text{Area} \times \text{Cost per m}^2$$​​

The area of the room:

​$$\text{Area} = 5.5 \times 3.75 = 20.625 \, \text{m}^2$$​​

Now, the total cost:

Total Cost = 20.625 × 800 = Rs. 16500 

Thus, the cost of paving the floor is Rs. 16,500
