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

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.

Answer 2

Answer:

Area of room=length * breadth

=3*4

=12

Area of one tile =0.5*0.5

=0.25

number of tiles is given by the formula,

number=area of room/area of one tile

So,

Number=

0.25

Thus 48 tiles will be used to cover an entire floor
