# A marble tile measures 12cm × 10cm. How many tiles will be required to cover a wall of size 4m by 3m? Also, find the total cost of the tiles at ₹22.50 per tile.

One tile=12×10=120cm,wall=4×3 =12m,1m=100cmso,12m=1200cm.to find no.of tiles =1200÷120=10.co

Total cost=22.50×10=225/-

I think it is correct
