    first one for example \[\frac{4}{16}=\frac{1}{4}\] so ratio of the perimeter is \[\frac{\sqrt{1}}{\sqrt{4}}=\frac{1}{2}\]

    yes \[\frac{75}{12}\] reduces conveniently to \[\frac{25}{4}\] now you can easily take the square root and get \[\frac{5}{2}\]

    similarly \[\frac{49}{9}\] take the square root directly get \[\frac{7}{3}\] etc got it?
