Answer:
Is there an error in the question? it has BC = 27 twice and we don't know much about the other sides. Anyway let's try
Step-by-step explanation:
You are told that to go from WXYZ to ABCD the scale factor is 2/3, which means that you multiply by 2/3. So to go the other way round, from ABCD to WXYZ which is what you want, you divide by 2/3, or multiply by 3/2.
So, to find XY you multiply the right side from ABCD by 3/2. I think BC is the right side?
So XY = 27 × 3/2
XY = 81 / 2 or 40.5 or 40 1/2
