Question

the floor of a room is 3 M wide and 4 long how many square tile of side 50 cm are required to cover the floor of the room ​

Answer 1

Answer:

48 tiles

Step-by-step explanation:

Area of rectangle = length×breadth

Area of the floor of room = 3×4 = 12m² = 1,20, 000 cm²

1m² = 10,000 cm²

Area of square = side×side

Area of 50 cm square tile = 50× 50 = 2500 cm²

No of tiles = area of floor / area of one square tile

No of tiles = 120000/2500

= 1200/25 = 48

48 tiles

So there are 48 square tiles in the room

Answer 2

Answer:-

According to the Question

It is given that,

• Length of room ,L = 3m = 300cm
• Breadth of room ,B = 4m = 400cm

• Side of square tiles ,S = 50cm

We have to calculate the no. tiles required to cover the floor of the room.

Firstly we calculate the area of room .

• Area of Room = Length × Breadth

Substitute the value we get

→ Area of Room = 300 × 400

→ Area of Room = 120000 cm²

Now, Calculating the area occupied by one titles .

• Area of Square tiles = side × side

substitute the value we get

→ Area of Square tiles = 50×50

→ Area of Square tiles = 2500cm²

So, the no. of titles = Area of Room/Area of Square tiles

→ No. of tiles = 120000/2500

→ No. of tiles = 1200/25

→ No. of tiles = 48

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