Answer:
Explanation:
Length of floor = 4m, breadth = 3m.
By the dimensions we can determine the floor is rectangular.
Therefore, area of rectangle = L x B
= 4 x 3
= 12
Therefore, area of rectangle is 12sq.m
Side of the square tile = 0.2m
Therefore, area of square tile = Side^2
= (0.2)^2
= 0.04
Therefore, area of tile is 0.04sq.m
No. of tiles required to fit the floor
= Area of floor / Area of tile
= 12 / 0.04
= 12 x 100 / 4
= 3 x 100
= 300
Therefore, 300 riles of required dimensions are needed to cover the floor.
