Given:
- Altitude of each tile = 10 cm
- Base of each tile = 4 cm
- Cost of polishing = Rs. 9.50 per dm^2
To Find:
- Cost of polishing the design
Approach:
1. Calculate the area of each tile.
2. Find the total area of the design.
3. Convert the area from cm^2 to dm^2.
4. Calculate the cost of polishing the design.
Calculation:
1. Calculate the area of each tile:
- The area of a parallelogram is given by the formula: Area = base x height.
- Here, the base of each tile is 4 cm and the height (altitude) is 10 cm.
- So, the area of each tile = 4 cm x 10 cm = 40 cm^2.
2. Find the total area of the design:
- The design consists of 1000 tiles.
- Therefore, the total area of the design = 1000 tiles x 40 cm^2 = 40000 cm^2.
3. Convert the area from cm^2 to dm^2:
- 1 dm = 10 cm, so 1 dm^2 = 100 cm^2.
- To convert cm^2 to dm^2, divide the area by 100.
- Therefore, the total area of the design in dm^2 = 40000 cm^2 / 100 = 400 dm^2.
4. Calculate the cost of polishing the design:
- The cost of polishing per dm^2 is given as Rs. 9.50.
- Therefore, the cost of polishing the design = 400 dm^2 x Rs. 9.50/dm^2 = Rs. 3800.
Therefore, the cost of polishing the design is Rs. 3800.
- Altitude of each tile = 10 cm
- Base of each tile = 4 cm
- Cost of polishing = Rs. 9.50 per dm^2
To Find:
- Cost of polishing the design
Approach:
1. Calculate the area of each tile.
2. Find the total area of the design.
3. Convert the area from cm^2 to dm^2.
4. Calculate the cost of polishing the design.
Calculation:
1. Calculate the area of each tile:
- The area of a parallelogram is given by the formula: Area = base x height.
- Here, the base of each tile is 4 cm and the height (altitude) is 10 cm.
- So, the area of each tile = 4 cm x 10 cm = 40 cm^2.
2. Find the total area of the design:
- The design consists of 1000 tiles.
- Therefore, the total area of the design = 1000 tiles x 40 cm^2 = 40000 cm^2.
3. Convert the area from cm^2 to dm^2:
- 1 dm = 10 cm, so 1 dm^2 = 100 cm^2.
- To convert cm^2 to dm^2, divide the area by 100.
- Therefore, the total area of the design in dm^2 = 40000 cm^2 / 100 = 400 dm^2.
4. Calculate the cost of polishing the design:
- The cost of polishing per dm^2 is given as Rs. 9.50.
- Therefore, the cost of polishing the design = 400 dm^2 x Rs. 9.50/dm^2 = Rs. 3800.
Therefore, the cost of polishing the design is Rs. 3800.
