The perimeter of a rectangular garden is 360 ft. What is the length of the garden?

1) the length of the garden is twice the width
2) the difference between the length and width of the garden is 60 ft

I don't struggle with 1. Clearly 2(l+w)=360 and we clearly have a substitution for w (w=l/2) but in the Official Answer, it appears as if we are to implicity assume that l>w to prove that B is sufficient. Why?

OA is D. I don't see how 2 can stand alone - L could be 60 or 120, depends on how you interpret difference.

given 2 * (l+w) = 360. what is l?
st 1) l=2w . substituting in the above equation we can get l
st 2) l-w = 60. solving for the 2 equations, we can get l
D

difference between length and width is 60 mean l-w = 60.

I have sympathy for your agony but for rectangles, length is always greater than width - it's a universally accepted standard.

Understood, makes sense. It seems that I'm challenging universally accepted standards, maybe I should be applying to Law School.

Don't worry. In most cases GMAT doesn't test such kind of concepts. In this particular case, I would interpret "the difference between the length and width of the garden is 60 ft" as l-w=60. But again, this example is rather an exception than rule: almost all GMAT questions are straightforward.
