hence distance is the total path covered 7.5 + 4 = 11.5 m = 1150 cm
but displacement is the shortest path covered now consider a right angled triangle the displacement we need to calculate will be the hypotenuse 7.5 is adjacent side 4 is the opposite side

7.5m west and 400cm = 4m north
hence distance is the total path covered
7.5 + 4 = 11.5 m = 1150 cm
but displacement is the shortest path covered
now consider a right angled triangle
the displacement we need to calculate will be the hypotenuse
7.5 is adjacent side
4 is the opposite side
therefore
(hypo)^2 = (adj)^2 + (opp)^2
= (7.5)^2 + (4)^2
= 56.25 + 16
= 72.25
(hypo)^2 = 72.25
hypo = root 72.25
hypo = 8.5 m = 850 cm
therefore displacement = 8.5 m = 850 cm
hope it helps
can u mark me as brainliest plz
