Distance walked by the person = 10 steps * 80 cm = 800 cm
Distance walked in the perpendicular direction = 40 * 80 cm = 320 cm
The final displacement of the person from starting position = diagonal of the right angle triangle traced by the person.
So magnitude of the displacement = √[800² + 320²] = 160√29 cm
