Question Statement:

A surveyor starts from point O and walks $12\text{ m}$ North. He then turns right (facing East) and walks $5\text{ m}$. The shortest straight-line distance from his current position back to starting point O is ________ $\text{m}$.

Answer Key:

13.0

Step-by-Step Solution & Explanation

By Pythagoras theorem on the right-angled triangle formed by North ($12\text{ m}$) and East ($5\text{ m}$) legs: $d = \sqrt{12^2 + 5^2} = \sqrt{144 + 25} = \sqrt{169} = 13.0\text{ m}$
