To find the total cost of polishing the floor,
we first need to calculate the area of each rhombus-shaped tile.
The area of a rhombus can be calculated using the formula: Area = (diagonal1 × diagonal2) / 2.
For each tile, the area would be (45 cm × 30 cm) / 2 = 675 cm².
Now, we need to convert the area from cm² to m².
Since 1 m = 100 cm,
1 m² = 10000 cm².
Therefore, the area of each tile in m² would be 675 cm² / 10000
= 0.0675 m².
To find the total cost of polishing the floor, we multiply the area of each tile by the number of tiles (3000) and the cost per m² (Rs. 4).
Total cost = Area of each tile × Number of tiles × Cost per m²
Total cost = 0.0675 m² × 3000 × Rs. 4 = Rs. 810
Therefore, the total cost of polishing the floor would be Rs. 810.
