Explanation:
each tile-
length-12cm
breadth- 10cm
wall
length-4m =400cm
breadth- 3m=300 cm
area of each tile = 10×12cm =120cm^2.
area of wall= 400×300=120000cm^2.
no of tiles required= area of wall/areaof each tile
= 120000/120 = 1000 tiles
cost of each tile= 2rs
cost of 1000 tiles= 2×1000 = 2000 rs
