distence=30+30+30 (2)^1/2=60+30 \sqrt {2}
displacement =
$= \sqrt{ {30}^{2} + {(30 - 30 \sqrt{2}) }^{2} } \\ = \sqrt{900 + 900 + 1800 - 1800 \sqrt{2} } \\ = \sqrt{3600 - 1800 \sqrt{2} } \\ = 30 \sqrt{4 - 2 \sqrt{2} } m$

Answer 2

Displacement is zero as the particle comes to the same point again
Distance is sum of all the paths-
30+30+30√2=102m approx
