Answer:
7500
Step-by-step explanation:
Length of the floor=18m=18X100=1800cm
Breadth of the floor=15m=15X100=1500cm
Area of the floor =l X b=1800 cm X 1500 cm
Area of the tile =side X side=30cm X cm
total number of tiles=Area of the floor/Area of the tile
Number of tiles =(1800 cm X 1500 cm)/ (30 cm X 30 cm)=3000 tiles
Cost of one tile = Rs 2.50
Total cost of 3000 tiles = Rs 2.50 X 3000 =Rs 7500 answer
