**Bosnian**, Sunday, November 7, 2010 at 5:13pma-lenght of two sides of triangle

c- lenght of third side of triangle

c=2a-4

Perimeter:

P=a+a+c= 2a+(2a-4)= 2a+2a-4= = 4a-4

=4(a-1)

P=16

4(a-1)=16 Divided with 4

a-1= 16/4

a-1= 4

a=4+1= 5

a=5 meters

c=2a-4 = 2*5-4 = 10-4= 6

c=6 meters

Perimeter=a+a+c=5+5+6=10+6= 16 meters
