.

QR is the side with the altitude PM.

PR is the side with the altitude QT.


You can calculate the area of the triangle PQR by two ways.


One way is      Area = ...


Another way is  Area = ...


Since the area is the same, it gives you an equation


    .. = ..,   or   . = ..


Hence,  |PM| =  =  = 3.5 cm.     ANSWER

Solved.
