Răspuns:
135 Radical din 66
Explicație pas cu pas:
{4,5,6} D.P {AC,BC,AB} AB:BC=1 R3 => 6K:5K=1 R3 => 5K+3=6K => K=3
AC=4K AC=4x3=>AC=12CM Pabc=12+15+18=45CM
BC=5K BC=5x3=>BC=15CM
AB=6K AB=6x3=>AB=18CM
Pabc=[tex]\sqrt{45(45-12)*(45-15)*(45-18)}\\[/tex]
Pabc=[tex]\sqrt{45*30*33*27\\}[/tex]
Pabc=[tex]\sqrt{1202850}[/tex]
Pabc=[tex]\sqrt[135]{66}[/tex]
