if QS = 10 then QM = 5 5^2 is 25 right?

let midpoint of QS = A sqrt (11^2  5^2) = AR AR = sqrt (12125) AR = sqrt (96) AR = 4 sqrt (6) PM + AR = PR + MA PM = PR/2 PR/2 + 4 sqrt 6 = PR + MA lol =)))

How u did @thushananth01 ? Can u say the reason please? U r absolutely right.

ok first find the full length of PR u can do this first by using pythagoras theorom then u have to add both and divide by 2 to get the midpoint as i gve previous with the radical..that was the length from P to M now we know PM and PQ plus the angle QPM v can find using the sin rule then i got the angle as 45.6 then finally the cose rule\[p^{2}= q^{2} + m^{2}  2qm (cos P)\] \[7^{2}+7.35^{2}  2 \times 7 \times 7.35 \cos 45.6 = p^{2}\rightarrow QM^2\]

\[\frac{\sqrt{24} +\sqrt{96}}{2}\rightarrow PM\]
