Side length of Quadrilateral, a=2,3,5, and 6.
Side length of Quadrilateral, b=4,5,8 and 10
⇒Comparing the Ratio of the Corresponding Sides of two Quadrilateral a and b

As,the ratio of corresponding opposite sides are not equal.That is these two Quadrilateral are Not Similar.
So, We can say that , Quadrilateral b, is not scaled copy of Quadrilateral a.
