A tile having dimension of 40 cm into 12 cm is used to to whole area of floor who is area is 900 cm square find the total number of tiles need to cover whole area of flour ​

Answer 1

Length of floor = 4 metres

breadth of the floor = 3 metres

Area of the floor = 4m * 3m = 12 sq.m

lenght of the tile = 20cm

area of the tile = 20 * 20 = 400cm^2

12 sq. m = 120000 sq. cm

no.of tiles required = 120000/400 = 300 tiles

therefore, you require 300 tiles to cover your floor
