Pooja starts from her house, walks 200 m northward, then turns 45° to the right and walks 70 m. After that, she turns 90° to the right and walks another 70 m. What is the approximate shortest distance between her current location and her house?

Pooja starts from her house, walks 200 m northward, then turns 45° to the right and walks 70 m. After that, she turns 90° to the right and walks another 70 m.

Explanation:
Logic: Use components + Pythagoras.
Step-by-step:
1st: (0, +200)
2nd: 70 at 45° → (≈50 East, ≈50 North)
3rd: 70 at SE → (≈50 East, ≈−50 North)

Net:
East = 50 + 50 = 100
North = 200 + 50 − 50 = 200

Distance = √(200² + 100²) = √(40000 + 10000) = √50000 ≈ 223 m

Final Answer:
223 m

Final Correct Option:
D
