OPtion

1. 2.96
2. 7.5
3. 6.4
4. 2.50
5. 2.25
6. 3.25
7. 3.30
8. 3.50
9. 4.20
10. None of the above

Solution

Length of the tile =(Total cost of tiling /Rate per m tile)

=(8100/45)m=180m
As the tiles covers the whole room.

So, Area of the room = Area of the tiles

=(180×35/100)square m= 63 sq m

∴ Breadth of the room =(Area/Length)=(63/28)m

= 2.25 m
