A rectangular path of 60 m length and 3 m width is covered by square tiles of side 25 cm. How many tiles will there be in one row along its width? How many such rows will be there? Find the number of tiles used to make this path?

Answer:

Given, length of path = 60 m      and width of path = 3 m    Side of squares tile = 25 cm                                 \[=\frac{25}{100}m=0.25\,m\]                                                                                           [\[\because \] 1 m = 100 cm] Diagram of path is shown below             Number of tiles in one row along width             \[\text{=}\frac{\text{Width}}{\text{Side}\,\,\text{of}\,\,\text{one}\,\,\text{tile}}\]             \[\text{=}\frac{3}{0.25}\]             \[=\frac{3\times 100}{25}=12\]                                                                                                              Number of rows \[\text{=}\frac{\text{Length}}{\text{Side}\,\,\text{of}\,\,\text{one}\,\,\text{tile}}\]                         \[\text{=}\frac{60}{0.25}\]                                                                                                                                             \[\text{=}\frac{60}{25}\times 100=240\] Also, number of tiles = Number of tiles in one row \[\times \] number of rows \[=12\times 240=2880\].
