No, I do not agree with Jada.
Quad A has 3, 6, 6, 9
Quad B is a scale of A with shortest length being 2
A scale is basically a fraction or a ratio. The scale of Quad A to B is 3/2 since Quad A's shortest length is 3.
Using the scale factor of 3/2, we can determine the rest of Quad B's demensions through cross multiplication.
3/2 = 6/4
3/2 = 9/6
Quad B's demensions are 2, 4, 4, 6.
