I can not find enough rules to figure this out, please help
I know this much but I dont know where to start on the problem
Let the crossing point between AQ and PM B.
PA+AB+PB=PA+AQ+QB+PB
=(PA+AQ)+(PB+BQ)
=(PA+AN)+(PB+BM)
=PN+PM
=22cm
OK, thanks, so that makes it easy than.
BM = QB
AN=AQ
AB=BM+AN
thanks again
