The distance AB rounded to the nearest tenth =

Whitepunk [10]

it gives you the formula, so all you have to do is plug in the coordinates

$d = \sqrt{ {( - 1 + 3)}^{2} + {( - 1 - 1)}^{2} } \\ d = \sqrt{ {(2)}^{2} + {( - 2)}^{2} } \\ d = \sqrt{ 4 + 4 } \\ d = \sqrt{8} \\ d = 2 \sqrt{3} = 3.4641... \\ \\ d = 3.5$
