Perimeter of rectangular field is P=2L%2B2W
if P=%283%2F5%29km and it's length is twice its breadth, L=2W, then we have
%283%2F5%29km=2%2A2W%2B2W..............convert %283%2F5%29km in meters and solve for W
%283%2F5%29km=%283%2F5%291000m=%283000%2F5%29m=600m
600m=4W%2B2W
600m=6W
600m%2F6=W
W=100m
find the length:
L=2W
L=2%2A100m
L=200m
so, dimensions of the field: 200m by 100m
