Area that needs to be covered is the area of lawn ,area of lawn =l*b
12*10 = 120 m sq = 1200000 cm sq (1 m sq= 100*100 cm sq = 10,000 cm sq)
area of tile is =side*side
=25*25 =625 cm sq
number of tiles required = 1200000/625 =1920 tiles required
cost of 1 tile = rs 8
cost of 1920 tiles = 1920*8 = Rs 15360
