    Answer:

    Answer

    (i) Total distance travelled =3+4+9=16 km

    (ii) The body travels a total distance of 12 km in east direction i.e. towards x-axis.

    And it travels a distance of 4 km in North direction, i.e. towards y-axis.

    Hence, resultant displacement is

    =

    12

    2

    +4

    2

    =

    144+16

    =

    160

    =12.6km
