Let breadth of field be 'x' m
=> length of field = 2x m

Meghna jogged along the perimeter of field.
∴ 1 round = 2(x+2x) = 6x m
∴ 5 rounds = 5*6x = 30x m
=> 3000 m = 30x m
=> x = 100m

∴ Breadth = 100m
∴ Length = 2(100) = 200m

Perimetre of rectangle=2×(2x+x) She jogged 5 times so,5×6x=30x 30x=3000m X=100m L=2x=2×100=200m
