area of room = 4.8 × 3.2 = 15.36 m
1 m^2 = 10000 cm
area of square marble =10 ×10 =100 cm
number of tiles required to cover the floor =
10000÷100 =100 tiles
cost of per dozen tiles = 18
cost of each tiles = 18 ÷ 12 =1.5
cost of 100 tiles =100 × 1.5 =150
1 m^2 = 10000 cm
area of square marble =10 ×10 =100 cm
number of tiles required to cover the floor =
10000÷100 =100 tiles
cost of per dozen tiles = 18
cost of each tiles = 18 ÷ 12 =1.5
cost of 100 tiles =100 × 1.5 =150
