Explanation:

- The man starts by walking 20 meters north.

- He turns right (which is east when facing north) and walks 3 meters.

- Next, he turns left (which makes it north again) and walks 4 meters.

- From this position, he walks 4 meters towards the east.

- We need to determine his final position relative to the starting point.

Analysis for the Options:

- Option 1: 25 m east

- Incorrect. It does not account for the northern direction component of his walk.

- Option 2: 25 m north-east

- Upon calculating, the path forms a right-angled triangle. Using the Pythagorean theorem, his final distance from the start is \(\sqrt{(3+4)^2 + (20+4)^2} = \sqrt{49 + 576} = \sqrt{625} = 25\) meters.

- The direction is north-east because he moved both north and east.

- Correct Answer

- Option 3: 20 m north

- Incorrect. It does not take the eastward movement into account.

- Option 4: 24 m north

- Incorrect. Again, it ignores the eastward component.
