Srinija walked 9 km west from her home, then turned south and walked 11 km. Then she walked 13 km towards east and finally 4 km towards west. Now at what distance is Srinija from its initial position? MCQ with Answer and Explanation

Explanation:
Take A as reference. A is 30 m north of E. E is 60 m south of D, so D is 30 m north of A. F is 50 m east of A, so F is at (50,0). F is 40 m south of B, so B is 40 m north of F at (50,40). C is 50 m west of B, so C is at (0,40). Hence C is 40 m north of A.
