Answer:
960 tiles
Rs. 24000
Step-by-step explanation:
length of floor = 8 m = 800 cm
width of floor = 6 m = 600 cm
Area of floor = 800 cm × 600 cm
= 480000 cm²
Area of tile = 25 cm × 20 cm
= 500 cm²
Number of tiles required = Area of floor
__________
Area of tile
= 480000/ 500
= 960 tiles
Cost per tile = Rs. 25
Hence total cost = 960 × 25
= Rs. 24000
