Answer:
Given details:
Man travels 1.5 m in a direction , 2 m in south , 4.5 m east.
It is assumed that the man travels 1.5 m in east ( since it is not mentioned in the question)
Solution:
Total distance travelled by the man = 1.5+2+4.5 = 8 m
Resultant displacement can be found using the Pythagoras theorem.
Resultant displacement will be given by the hypotenuse, if the distance in east direction (i.e.) 1.5+4.5= 6 m is considered as base of the triangle and distance in south direction (i.e.) 2 m is considered as height of the triangle.
Resultant displacement = √(6² + 2²) = √40 = 2√10 m
