Question

find the number of square tiles required to cover the floor of a room whose length is 4m and width 3m if each square tile is of side 0.2m answer

​

Answer 1

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.
