Answer

$d=\sqrt{101}\text{ units}$

Work Step by Step

Using the Distance Formula, then the distance between $ (8,5)\text{ and } (-2,4) $ is \begin{array}{l} d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2} \\\\ d=\sqrt{(8-(-2))^2+(5-4)^2} \\\\ d=\sqrt{10^2+1^2} \\\\ d=\sqrt{100+1} \\\\ d=\sqrt{101}\text{ units} .\end{array}
