Answer:
the answer is 300 tiles
Step-by-step explanation:
Length of the floor = 4 metres
the 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
