Answer 2

Answer:

Step-by-step explanation:

first ,we can find the area of a single marble tile

so its area=10×12=120cm²=0.012m²

the total area of the wall=3×4=12m²

so number of marble tiles required=total area of the wall/area of a single marble tile

number of tiles=12/0.012=1000 tiles

total cost of the tiles=cost of one tile×no of tiles=2×1000=Rs.2000
