I feel like QR=22. What do you think? (I'm also pretty sure I'm not right.)
*QF
no, QF=27
because DC/DR= 2/3 and 18 is 2/3 of 27

i think its 24 but not much sure on this
Oh no, I'm not right
DC/DR = 12/16 = 3/4 = 18/QF QF = 4*18 / 3 = 24
nubeer, I think you were right.
Thanks, you guys!

Yeah, I think that they were supposed to be similar because we just finished talking about similarity.
