Pritam walks 15m towards south then turning to his right he walks 30m ...
Pritam’s starting point is at A.
Final position is E.
AE = A B + BE
= AB + CD
= 15 + 20
= 35 m
Final position is E.
AE = A B + BE
= AB + CD
= 15 + 20
= 35 m

Pritam walks 15m towards south then turning to his right he walks 30m ...
Given information:
- Pritam walks 15m towards south.
- He then turns right and walks 30m.
- He turns left and walks 20m.
- He turns left again and walks 30m.
To find: How far Pritam is from his starting position.
Solution:
Let's assume that Pritam's starting position is the origin (0,0) on a coordinate plane.
- Pritam walks 15m towards south:
- This means he moves 15 units in the negative y-direction.
- His new position is (0, -15).
- Pritam turns right and walks 30m:
- Turning right means he moves in the positive x-direction.
- He moves 30 units in the positive x-direction.
- His new position is (30, -15).
- Pritam turns left and walks 20m:
- Turning left means he moves in the positive y-direction.
- He moves 20 units in the positive y-direction.
- His new position is (30, 5).
- Pritam turns left again and walks 30m:
- Turning left means he moves in the negative x-direction.
- He moves 30 units in the negative x-direction.
- His final position is (0, 5).
Using the distance formula, we can calculate the distance between Pritam's final position and the origin (starting position):
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
= sqrt((0 - 0)^2 + (5 - 0)^2)
= sqrt(0 + 25)
= sqrt(25)
= 5 units
Therefore, Pritam is 5 units away from his starting position.
Answer: b) 35m
