Ellis's backyard has a 6.25\,\text{m}6.25m6, point, 25, start text, m, end text by 6.25\,\text{m}6.25m6, point, 25, start text, m, end text patio. She would like to build a 1.5\,\text{m}1.5m1, point, 5, start text, m, end text wide extension around 333 sides of the patio, as the figure shows. She will buy 0.25\,\text{m}0.25m0, point, 25, start text, m, end text by 0.25\,\text{m}0.25m0, point, 25, start text, m, end text tiles that come 252525 to a package.

How many packages does Ellis need to buy to build the extension?
