Jeremiah uses bamboo rods to make the frame of a tailless kite. He ties three bamboo rods together to form a right triangle PQR. He then ties another rod from P that meets RQ at a right angle. Segment PS in the figure below represents this rod and it is 6 inches long.
Which of the following could be the lengths of segments QS and SR?
QS = 4 inches, SR = 9 inches
QS = 6 inches, SR = 30 inches
QS = 2 inches, SR = 3 inches
QS = 16 inches, SR = 20 inches

Hint:
QS*SR = (PS)^2
jimthompson5910 (jim_thompson5910):
So
QS*SR = 6^2
QS*SR = 36
