Question

A boy walks 4 km South and then
3 km West. Find how far is he from the
2.
starting point.​

Answer 1

Answer:

5 km

Step-by-step explanation:

step 1: If we take initial point as point A

step 2: if we take the point when boy moves to west as point B.

step 3 : if take the final point as point C.

BY JOINING ALL POINT WE GET A RIGHT ANGLED TRIANGLE.

step 4 : By pythogoras theorem

${p}^{2} + {b}^{2} = {h}^{2}$

${4}^{2} + {3}^{2} = {h}^{2}$

$16 + 9 = {h}^{2}$

$25 = {h}^{2}$

$\sqrt{25} = h$

$h = 5km$
