The idea
Three equal sides of a square leave you exactly one side-length away from the start, at right angles to where you began.
Shortcut. East 8 and west 8 cancel, so only the 8 m north leg survives as displacement.
Common trap. "8√2 m" — picturing him at the opposite corner of the square; after three sides he is at the corner next to the start.
