Final answer:
Unable to provide the length of YZ in the similar parallelogram without full information; typically, one would use the property of corresponding sides being in proportion in similar figures to solve for lengths.
Step-by-step explanation:
The student's question involves determining the length of a side in a similar parallelogram. Based on the information provided, which seems to be incomplete or out of context, it's not possible to calculate the length of YZ. In questions involving similar figures like parallelograms, the ratio of corresponding lengths remains constant. If complete information was provided, such as the lengths of corresponding sides in both parallelograms or the scale factor of their similarity, then the length of YZ could potentially be calculated using the property of corresponding sides being in proportion.
