Question

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!

Answer 1

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
