Calculati perimetrul unui triunghi cu laturile a,b,c care au lungimile:a) a=1,5 m; b=73 cm; c=20 dm; b) a=30dm; b=0,4 dam; c=0,05 hm; c) a=80mm; b=0,7 dm; c=0,00005 km. VA INPLOR AJUATI-MĂ!!!!!!!!!Ofer coroana!
a) P=a+b+c a=1.5m=150 cm b=73 cm c=20dm=200cm Deci •P=150+73+200=423 cm b) a=30dm=300cm b=0.4 dam=400cm c=0.05hm=500cm •P=1200cm c)a=80mm=0.8cm b=0.7dm=7cm c=0.00005 km=5cm •P=12.8cm
