What is the shortest distance between Point P and Point R?

In certain coding language, the directions are coded as per below conditions. Y@Z means – Y is North of Z Y%Z means – Y is South of Z Y#Z means – Y is East of Z Y $ Z means – Y is West of Z Y@#Z means- Y is North East Z The distance between two point is either 8 m or 11
m. @ means the distance between the two points is 8m % means the distance between the two points is either 11m. YZ > AB Means the distance between point Y and Z is greater than that of point L and
M. Example: Y @ Z means Y is north of Z and the distance between Y and Z is 8m. M # N, O % N, P @ Q, R # Q, P $ O, R @ S, T # S NO = ST, QR > RS,PO < MN = ST
