Question

A tile is a square of side 30cm. how many such tiles would be required to cover the floor of a room of size 6m by 3m

Answer 1

Hello mate,
The side of the square tile=30 cm =0.3 m
now area of the square tile=side*side=0.3*0.3=0.09 m square
Now the length of the room=6 m
it's breadth=3 cm
So, area of rectangle=length *breadth=6 m*3m=18m square..
Now, number of tiles required to cover the floor=18/0.09 =200 tiles
So, it requires 200 tiles to cover the floor

hope helped and plz mark it...

Answer 2

Hey mate

Here's your answer

Q - A tile is a square of side 30cm. how many such tiles would be required to cover the floor of a room of size 6m by 3m ?

: Firstly, we will convert m into CM beacuse tile side is in CM.

6 m = 6 X 100 = 600 cm
3 m = 3 x 100 = 300 cm

Area of room
= L X b
= 600 X 300
= 180000 cm²

Area of 1 tile
= S x S
= 30 X 30
= 900 cm²

No. of tiles will require
= Area of room / Area of 1 tile
= 180000/900
= 200 tiles

Hope this helps you
