distance total = 20 + 30 = 50 m
displacement = 36.05 m
displacement = 36.05 m

body traveled from a to b =20 m
the distance moved from right angle = 30 m
if we see the figure which will form right angled triangle
so displacement will be the hypotenuse of the triangle
hypotenuse => a²+b²=c²
let 20 m be a ( base)
let 30 m be b ( perpendicular)
=> (20)² + (30)² = c²
=> 400 + 900 = c²
1300 = c²
c = 36.05 m
the distance moved from right angle = 30 m
