#### Answer

$13$

#### Work Step by Step

RECALL:
The distance between the points $(x_1, y_1)$ and $(x_2, y_2)$ can be found using the distance formula
$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
Use the formula above to obtain:
$d=\sqrt{(14-2)^2+(8-3)^2}
\\d=\sqrt{12^2+5^2}
\\d=\sqrt{144+25}
\\d=\sqrt{169}
\\d=\sqrt{13^2}
\\d=13$
