$d\approx 4.12 \text{ units} $

Work Step by Step

Using $d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$ or the Distance Formula, then the distance, $d$, between the given points $( 3,5 )$ and $( 4,1 )$ is \begin{array}{l}\require{cancel} d=\sqrt{(3-4)^2+(5-1)^2} \\\\ d=\sqrt{(-1)^2+(4)^2} \\\\ d=\sqrt{1+16} \\\\ d=\sqrt{17} \\\\ d\approx 4.12 \text{ units} .\end{array}
