Answer:
3 tiles
Step-by-step explanation:
l=3m
b=4m
the area of rectangle is4×3=12
=12m
the area of square is 20×20=400cm
=4m
12/4=3
3 tiles required to cover the floor
Length of room = 4m
Breadth of room = 3m
Area of room = lb = 4 * 3 = 12m2
Side of tile = 20cm = 0.2m
Area of tile = s*s = 0.2 * 0.2 = 0.04m2
No. of tiles = (area of room)/(area of tiles)
= 12/0.04
= 300
