One more math problem puzzle part...any help appreciated: Semi-regular hexagon GHJKLM is circumscribed by circle O. If GH = 2 HJ = JK = 2 KL = LM = 2 MG and if GK = 12, determine the perimeter of the hexagon.

I don't understand your notation. Do you really mean "GH= 2HJ= JK= 2KL= LM= 2MG"- that is, that Gh, KL, and MG are equal length while HJ, JK, and LM are twice that length?
