Explanation:

- Let’s assign coordinates for clarity:

- Let’s put point R at (0,0).

- Q is 15m west of R ? Q: (-15,0)

- P is 10m north of Q ? P: (-15,10)

- S is 10m north of R ? S: (0,10)

- W is 8m east of S ? W: (8,10)

- T is 25m south of S ? T: (0, -15)

- U is 8m east of T ? U: (8, -15)

- V is 20m north of U ? V: (8,5)

- Distance from R (0,0) to V (8,5):

- Use distance formula: v[(8-0)² + (5-0)²] = v[64 + 25] = v89m

- Option 3: v89m is correct.

- Option-wise:

- 1: 10m – too short

- 2: 15m – not matching calculations

- ?? 3: v89m – matches calculation

- 4: 2v3m – too short

- 5: None of these – not needed
