Rectangle Z is not a scale drawing of Rectangle Y.

This is because there is no equal sides where it makes up the constant proportionality.

6/4 (= 3/2) in the left and right sides of the rectangle (Y/Z)

4/3 in the top and bottom sides of the rectangle (Y/Z)

As you can see 3/2 is not equal to 4/3 of scaling, so therefore it is not a scaling.
