Let L and B are the length and breadth of rectangle

Given that L=60 m=6000 cm

B=3 m=300 cm

Side of the square tile =25 cm

Number tiles will there be in one row along its width

⇒

side of the a tile

width of the path

=

25

300

=12

Number of the rows =

side of a tile

length of the path

=

25

6000

=240.

Total number of tiles used =240×12=2880
