Two sides of a triangle have the same length. The third side measures 4 meters less than twice the common length . The perimeter of the triangle is 16 meters. What are the lengths of the three sides?

Bosnian,
alenght of two sides of triangle
c lenght of third side of triangle
c=2a4
Perimeter:
P=a+a+c= 2a+(2a4)= 2a+2a4= = 4a4
=4(a1)
P=16
4(a1)=16 Divided with 4
a1= 16/4
a1= 4
a=4+1= 5
a=5 meters
c=2a4 = 2*54 = 104= 6
c=6 meters
Perimeter=a+a+c=5+5+6=10+6= 16 meters
