Answer:
3 yd
Step-by-step explanation:
I have set up a equation based on the perimeter formula and the measurements given.
18 = 2(6 + w)
Solving for 'w', which would be the width:
[tex]18=12+2w\\\\12+2w=18\\\\12-12-2w=18-12\\\\2w=6\\\\\frac{2w=6}{2}\\\\\boxed{w=3}[/tex]
The width should be 3 yd.
Hope this helps.
