Answer:
16!!!!!!!!!!
Step-by-step explanation:
8+8=16
16+16=32
16+32=48
48/3=16
Firstly we need to find perimeter of rectangle
[tex]P = 2(w + l) \\ P = 2(16 + 8) = 48[/tex]
So the length of wire is 48in
Now we can find length of triangle's side.
All of sides are equal, so
[tex]l = 48 \div 3 = 16[/tex]
Answer: the length of side is 16in
