Answer:
1950 tiles will be required and the cost of the tile is Rs 15,600
Step-by-step explanation:
Length of the floor= 12m= 1200cm
Breadth of the floor = 10 m= 1000cm
Area of the floor = 1200cm × 1000cm
= 12,00,000 cm²
Side of a square tile = 25 cm
Area of a square tile= 25cm × 25cm
= 625 cm²
No. of square tiles to cover the floor = 1200000cm²÷ 625 cm²= 1950
Now, cost of a tile = Rs 8
cost of 1950 tiles = 1950 × 8
= Rs 15600
