Concept:The final displacement is found using Pythagoras theorem, and the direction is decided by the turns taken.Explanation:Ramesh first moves 30 m toward the east.Taking a right turn from east means he now faces south.He then moves 40 m toward the south.These two displacements are perpendicular.So, displacement from the initial point is:(30)2+(40)2​=900+1600​=2500​=50 mThe direction is toward the south-east.
