In the above answer, we are calculating the cost of cleaning the floor at the rate of 50 paise per square centimeter. 
The total area of the floor is 20000 cm2, which is calculated by multiplying the number of tiles (200) with the area of a single tile (20 cm * 5 cm). 
Finally, we multiply the total area of the floor (20000 cm2) with the rate of cleaning (0.50 paisa/cm2) to get the cost of cleaning the floor (Rs. 10000).

Step 1: Calculate the Area of One Tile
To determine the cleaning cost, we first need to calculate the area of one parallelogram tile.
- Base: 20 cm
- Altitude: 5 cm
The formula for the area of a parallelogram is:
- Area = Base × Altitude
Calculating the area:
- Area = 20 cm × 5 cm = 100 cm²
Step 2: Calculate the Total Area of the Floor
Since there are 200 tiles on the floor, we can find the total area by multiplying the area of one tile by the total number of tiles.
- Total Area = Area of One Tile × Number of Tiles
Calculating the total area:
- Total Area = 100 cm² × 200 = 20,000 cm²
Step 3: Calculate the Cleaning Cost
The cost of cleaning is given at the rate of 50 paise per square centimeter. We need to convert this into rupees for easier calculation.
- Cost per cm²: 50 paise = 0.50 rupees
Now, calculate the total cleaning cost:
- Total Cost = Total Area × Cost per cm²
Calculating the total cost:
- Total Cost = 20,000 cm² × 0.50 rupees = 10,000 rupees
Conclusion
The cost of cleaning the floor, which consists of 200 tiles of parallelogram shape, amounts to:
- Total Cleaning Cost: 10,000 rupees
This comprehensive calculation ensures that you understand how to derive the cleaning cost from the area of the tiles.
