a boy moves 30m towards east and turned left. now he is facing north. there he travelled 40m.
so total distance travelled= 30+40= 70m
if we look at it then it forms a right angle triangle.
base and height are given= 30 and 40cm
so we have to fine the hypotenuse
so h²= 30² +40²
⇒ h² = 900+1600
⇒ h= √2500
∴ h= 50
so the displacement is 50m. (distance between starting point and current position.)
