Answer 1

Answer:

The required distance is

$= \sqrt{ {(1 - 2) }^{2} + {(3 </strong><strong>+</strong><strong> 5)}^{2} } \: \: unit$

$= \sqrt{ { ( - 1)}^{2} + {( </strong><strong>8</strong><strong>)}^{2} } \: \: unit$

$= \sqrt{1 + </strong><strong>6</strong><strong>4} \: \: unit$

$= \sqrt{</strong><strong>6</strong><strong>5} \: \: unit$
