Question

Vijay wants to cover the floor of a room 3 m wide and 4 metre long by square tiles if each square tile in side 0.5 then the number of tiles required to cover the floor of the room​

Answer 1

Given;

• a rectangle room
• l = 4m
• b = 3m

• a square tile
• s = 0.5m

Thus area of room ;

• A = lb
• A = 3 × 4 = 12m²

Thus area of 1 tile ;

• A = s²
• A = 0.5² = 0.25²

Let there be n tiles covering the entire room;

Thus n =

• n × ar.(1 tile) = ar.(floor)
• n × 0.25 = 12
• n = 12 / 0.25
• n = 12 / (1/4)
• n = 12 × 4
• n = 48 tiles

Answer 2

Total area of tiles must be equal to the area of the floor of the room.

• Length of the room = 4 m
• Breadth of the room = 3 m

Formula used:-

• Area of the floor = length × breadth

Putting the values according to the formula:

=> Area of the floor = 4 m × 3 m

=> Area of the floor = 12 sq m

Area of one square tile = Side × Side

=> Area of one square tile = 0.5 m × 0.5 m

=> Area of one square tile = 0.25 sq m

Number of tiles required = Area of the floor/Area of one tile

=> Number of tiles required = 12/0.25

=> Number of tiles required = 1200/25

=> Number of tiles required = 48 tiles

Hence:-

• The number of tiles required to cover the floor of the room is 48 tiles.
