Answer:
In parallelogram PSQSR, Pq represents the length of the side PQ.
Since PSQR is a parallelogram, opposite sides are equal in length. Therefore, Pq is equal in length to the side SR, which is opposite to Pq in the parallelogram.
So, if the length of SR is given, then Pq is also equal to that length. If the length of SR is not given, then Pq cannot be determined.
