I think ans should be A.

1. width of rect = side of sqr.
as length > width, length of rec > side of sqr
hence area of rect > area of sqr

2. if length of rect = l, width of rect = w, side of sqr=a
l = a^2
now l x w = a^2 x w , which might be greater than a^2 if w>1 or less than a^2 if w<1

so not insuff.
