I honestly don't know how to describe the question. I can't seem to paste the triangle onto this space.. but i'll describe the question fully IN WORDS.. hope you guys'd help by sketching it out on your notepad. Thanks in advance... here goes..

PQR is a right angled triangle, with angle PQR = 90. M is the mid-point of PR. QM = 6.5cm and QR is 5cm. What is the length of PQ?
The answer is 12cm...
I've tried to see if I could use similar triangles and all... but to no avail...

Thanx guys~~
