Medians in triangle

The median of the isosceles triangle has a length of 3 cm. Determine the size of its sides if its perimeter is 16 cm.

Correct answer:

a =  5 cm
b =  5 cm
c =  6 cm
a2 =  6 cm
b2 =  6 cm
c2 =  4 cm

Step-by-step explanation:

p=3 cm o=16 cm c=2 p=2 3=6 cm  a=(oc)/2=(166)/2=5 cm
b=a=5=5 cm
a2=2 3=6 cm
b2=a2=6=6 cm
c2=o(a2+b2)=16(6+6)=4 cm
