In the question we have floor tiles that are 25 cm squares. Therefore the area of each tile is 25 cm squares.
The length of rectangular lawn is 12 m
The breadth of the rectangular lawn is 10 m
The area of the rectangular lawn is l×b
. Therefore on substituting the value of length and breadth we have
⇒A=l×b=12×10On simplifying
⇒120
m squares.
The number of tiles required for the rectangular lawn is the ratio of the area of the rectangular lawn to the area of a tile.
number of tiles = area of rectangular lawn
____________________
area of tile
Substituting the values to the above formula. since the area of rectangular lawn is in the metre square and the area of tile is in the centimetre square. So let us convert the area of tile to the unit to metre.

____________________
area of tile
Substituting the values to the above formula. since the area of rectangular lawn is in the metre square and the area of tile is in the centimetre square. So let us convert the area of tile to the unit to metre.
number of tiles = 12025×10−4
⇒120×10425⇒48000
Therefore the number of tiles is 48,000.
The cost of one tile is Rs.8
Therefore the cost of 48,000 tiles is 8×48000
On simplifying we have
⇒384000
Therefore the total cost is Rs. 3,84,000
