A→D east 11m. D→F north 7m (left turn). F→T east 10m (right turn). T→G south 8m (right turn). G→K south 4m. K→M (M south of F). M→O right turn 4m. O→N 11m (N south of A). Shortest distance A to N?

Correct answer: 1m

Solution

A(0,0), D(11,0), F(11,7). Right(east)→T(21,7). Right(south)→G(21,-1). S→K(21,-5). K to M: west to x=11 → M(11,-5). Right turn→north → O(11,-1). West 11m → N(0,-1). Distance=√(0+1)=1m.
