If the perimeter of a rectangular garden plot is 80 meters, which of the following could be the length of one of its sides?
I. 30 meters
II. 40 meters
III. 50 meters
(A) I only
(B) II only
(C) III only
(D) I and II
(E) II and III
\(2(l+b)=80 => l+b=40\)
Hence \(l=40-b\), so length can be anything less than or equal to \(40\)
Option D
