Since QR is parallel to NO, we can use the similarity of triangles to find the length of QP.

We have the proportion: QP/NO = QR/NQ

Plugging in the given values: QP/44 = 24/20

Cross multiplying: QP*20 = 44*24

Simplifying: QP = (44*24)/20 = 11*24/5 = 264/5 = 52.8

Therefore, the length of QP is 52.8.
