area ABCD = 924 cm^2
AF = CG = 27 cm
EF/FG = 21/22
area COB = 108 cm^2
FG*21FG/22 = 21FG^2/22 = 924*2
FG = √924*44/21 = 44 cm
EF = 21*2 = 42 cm
AE = CH = EF-AF = 42-27 = 15 cm
BG = DH = 2*COB/AF = 216/27 = 8,0 cm
CD = √8^2+15^2 = 17,0 cm
CB = √8^2+27^2 = 28,2 cm
AB = √36^2+27^2 = 45,0 cm
AD = √36^2+15^2 = 39,0 cm
17,0+28,2+45,0+39,0 = 129,2 cm
