Bonjour,
AD = FG = 100 m
AF = DG = 80 m
AB = BD = 100/2 = 50 m
BC = DE = EG = 80/2 = 40 m
AB + BC + CD + DE + EF + FG + GA = distance parcourue
Distance = 50 + 40 + CD + 40 + EF + 100 + GA
Distance = 230 + CD + EF + GA
CD^2 = BC^2 + BD^2
CD^2 = 40^2 + 50^2
CD^2 = 1600 + 2500
CD^2 = 4100
CD ~ 64 m
EF^2 = EG^2 + FG^2
EF^2 = 40^2 + 100^2
EF^2 = 1600 + 10000
EF^2 = 11600
EF ~ 107,7 m
GA^2 = AD^2 + DG^2
GA^2 = 100^2 + 80^2
GA^2 = 10000 + 6400
GA^2 = 16400
GA ~ 128 m
Distance = 230 + 64 + 107,7 + 128
Distance ~ 529,7 m
