  1. hint

    Given area of field = 3584m

    2

    length = 64 m

    We know area – length × breadth = l×b

    b=

    64

    3584

    =56m

    Now Perimeter of field = 2[l+b]

    =2[64+56]

    Perimeters of field = 2[120]= 240 m.

    for 5 rounds perimeter = 240×5=1200m

    Given speed of boy = 6 km/h = 6×

    18

    5

    =

    3

    5

    m/sec

    then time taken to cover 1200 m distance =

    5

    1200

    ×3

    Time = 240×3sec

    or Time =

    60

    240×3

    min=12min

    ∴ 12 min required to complete 5 rounds of field.
