Evan starts from point A and drives 12 km towards west.
He then takes a left turn, drives 6 km, turns left and drives 4 km.
He then takes a right turn and drives 2 km.
He then takes a right turn and drive 3 km.
He then takes a left turn and drives 3 km.
He takes a final left turn, drives 11 km and stops at point P.
