Question

tom wants to cover the floor of a room 3m with 4m long by squared tiles, if each square tile is of side 0.5 m , then find the number of tiles required to cover the floor of a room.​

Answer 1

Given:

✰ Length of the floor = 4 m

✰ Breadth of the floor = 3 m

✰ Length of each side of a square tile = 0.5 m

To find:

✠ The number of tiles required to cover the floor of a room.

Solution:

Let's understand the concept here! First we will find the area of the room by using the formula, then we will find the area of each side of a square tile. After that we will divide the area of the floor by the area of square tiles to get the number of tiles required to cover the floor of a room. One should be careful while doing the calculations in this case.

Let's find out...♪

✭ Area = length × breadth ✭

➛ Length of the floor = 4 m

➛ Breadth of the floor = 3 m

➛ Area of the floor = 4 × 3

➛ Area of the floor = 12 cm²

➛ Length of each side of a square tile = 0.5 m

➛ Area of a square tile = 0.5 × 0.5

➛ Area of a square tile = 0.25

Now,

➤ The number of tiles required to cover the floor of a room = Area of the floor/Area of a square tile

➤ The number of tiles required to cover the floor of a room = 12/0.25

➤ The number of tiles required to cover the floor of a room = (12 × 100)/25

➤ The number of tiles required to cover the floor of a room = 1200/25

➤ The number of tiles required to cover the floor of a room = 48

∴ 48 tiles are required to cover the floor of a room.

Answer 2

Given :

Tom wants to cover the floor of a room 3m with 4m long by squared tiles, if each square tile is of side 0.5 m.

To find :

Then find the number of tiles required to cover the floor of a room.

Solution :

Area of Room = Length × Breadth

= 3 × 4

= 12

Area of one Tile = 0.5 × 0.5

= 0.25

Total no. of tiles = Area of room/Area of Tile

= 12/0.25

= 48

Therefore 48 tiles are required to cover the floor of the room.
