Instructions

Read the below information carefully and answer the following questions.
Rahul moves 12 m in North direction from a point O to reach point A. He turns right and moves 15 m to reach point B. Then he turns left and moves 10 m to reach a point C. She turns right and moves 6 m to reach a point D. He again turns right and moves 1m to reach point E. He further turns right and moves 1m to reach point F

Question 23

Find the shortest distance between the initial position and final position?

Solution


In the North Direction Rahul has travelled (12 + 10 - 1)m = 21m.
In the East Direction Rahul has travelled (15+6-1) m = 20m.
By Pythagoras Theorem, total distance travelled => d
=> d = $$\sqrt{20^2+21^2}$$ = 29 m
