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
