Length of 4 width of 2=L+W=1/2 perimeter, because the whole perimeter is 2L+ 2W. The choices with whole numbers are:
5/1; both long sides are 5 units, and both short sides are 1 unit.
4/2
3/3, which is a square, a special case of a rectangle.
No other whole numbers work, if one assumes the length is the same or longer than the width.
