consider east-west direction along X-axis and north-south direction along Y-axis.
A = displacement along east direction = 5.5 i
B = displacement along north direction = 8 j
R = resultant displacement
Resultant displacement is given as
R = A + B
R = 5.5 i + 8 j
using Pythagorean theorem , magnitude of the resultant displacement is given as
|R| = sqrt(|A|² + |B|²) = sqrt((5.5)² + (8)²) = 9.7 blocks
