Solution

The correct option is B 13 m
Given, Tarun walks 12 m west followed by 5 m north.

The shortest distance between the starting point and school is the hypotenuse of the right-angled triangle formed.

Using Pythagoras' Theorem,
we get
shorted distance = $= 144 + 25$
$= 169$
$∴ s h o r t e d d i s t a n c e = \sqrt{169} m$ . = 13 m
