Answer: Not similar
Step-by-step explanation:
From the given graph, by using distance formula
For figure WXYZ with coordinates W(2,0), X(0,0), Y(0,3) and Z(2,3)
Since, YX is on y axis, then length of YX=
Similarly, WX is on x axis, then length of WX=
Now, for W'X'Y'Z' with coordinates W' (6, 0); X' (0, 0); Y' (0, 12); Z' (6,12), the length of W'X'=
The length of Y'X'=
We know that if two figures are similar then their corresponding sides are proportional.
Now, 

But,
,
Hence they are not proportional so they are not similar.
