b) D
c) A ​

Answer 1

Answer:

a)C is the right answer

Explanation:

Please mark me as brainliest

Answer 2

Explanation:

Displacement is the shortest distance from the starting point to the final destination.

Distance is the length of the path that is travelled.

a) Distance travelled = AB + BC = 4 + 5 = 9 cm Displacement is to be calculated by Pythagoras theorem, for the shortest distance between A and C is the length of AC.

AC^2 = 4^2 + 5^2

AC^2 = 16 + 25

AC^2 = 41

AC = √41

b) Distance travelled = AB + BC + CD = 4 + 5 + 4 = 13cm

Displacement = AD = 5 cm

c) Distance travelled = AB + BC + CD + DA = 4+5+4+5 = 18cm

There is no change in position, hence the displacement is 0.

I hope this helps. :D
