Answer
$2\sqrt{11}
\text{ units OR }\approx
6.633
\text{ units}$
Work Step by Step
Using the Distance Formula, $d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$, the distance between the given points is
\begin{array}{l}
\sqrt{(-\sqrt{5}-(-\sqrt{5}))^2+(-\sqrt{11}-(-3\sqrt{11}))^2}
\\\\=
\sqrt{0+44}
\\\\=
\sqrt{44}
\\\\=
\sqrt{4\cdot11}
\\\\=
2\sqrt{11}
\text{ units OR }\approx
6.633
\text{ units}
.\end{array}
