Answer 2

Answer :

2400 tiles is required to tile the floor.

Step-by-step explanation :

To Find,

• Number of tiles required.

Solution,

Given that,

• Length of a tile = 20cm long
• Breadth of a tile = 10cm wide

• Length of the floor = 8m
• Breadth of the floor = 6m

First, converting the length and breadth of the floor to centimetres,

Length :-

➞ ( 8 × 100 )cm

➞ 800cm ..... [ 8m = 800cm ]

Breadth :-

➞ ( 6 × 100 )cm

➞ 600cm ..... [ 6m = 600cm ]

As we know that,

Number of tiles = Area to be covered by tiles / Area of a tile,

Therefore,

Area of the floor :-

➞ 800cm × 600cm

➞ 480000cm²

Area of a tile :-

➞ 20cm × 10cm

➞ 200cm²

Now, the number of tiles are :-

➞ 480000 / 200 .... Cancelling two zeros from both numerator and denominator.

➞ 4800 / 2

➞ 2400

∴ Number of tiles required to tile the room is 2400 tiles.
