(A) I only (B) II only (C) III only (D) I and II (E) II and III

Perimeter = 2L + 2B If perimeter is 80 then 2L should be below 80 L should be below 40 (rectangle has L & B)

I only A

Not D because if L is 40 then perimeter will be 80 + 2B in that case (breadth of rectangle will be 0)

Mathematically width/length of the rectangle can be negligible and hence can be 0. essentially it will be a straight line. I am not sure how GMAT geometry treats this.

Thanks for clarifying and I agree that from GMAT stand point we can consider that a geometric figure must have dimensions because in GMAT concepts of calculus or complex numbers are not tested. Hence i will edit my solution accordingly.

But Mathematically there is a concept of Degeneracy Condition according to which a line segment is a degenerate condition of a rectangle as one of its side tends to 0

And in fact we have used this concept in GMAT Club forum -

You most definitely do not need consider degenerate polygons on the GMAT. The question you mention also does NOT consider degenerate triangles.

Yup got it . I mentioned this example because in this example as well as in similar examples some experts have assumed minimum area of triangle to be 0. so if that is possible then minimum area of rectangle can be 0 for this case. But let's not harp on this further and its safe to assume that in GMAT area cannot be 0. Thanks Bunuel for your great insights
