Solution
Given, Length of path = 60 m
And width of path = 30 m
Side of square tile = 25 cm
= `25/100` m ...[∵ 1 m = 100 cm]
= 0.25 m
Diagram of path is shown below
Number of tiles in one row along width = `"Width"/"Side of one tile"`
= `3/0.25`
= `(3 xx 100)/25`
= 12
Number of rows = `"Length"/"Side of one tile"`
= `60/0.25`
= `60/25 xx 100`
= 240
Also, number of tiles = Number of tiles in one row × Number of rows
= 12 × 240
= 2880
