Answer 2

Answer:

Distance =2(a+b)

Step-by-step explanation:

$distance \: formula \\ \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} }$

$\sqrt{( - a - a) {}^{2} + ( - b - b) {}^{2} } \\ \sqrt{( - 2a) {}^{2} +( - 2b) {}^{2} } \\ \sqrt{4a {}^{2} + 4b {}^{2} } \\ 2 \sqrt{a {}^{2} + b {}^{2} }$

$2(a + b)......$
