Answer:
The width is 79 yards
Step-by-step explanation
Okay, so the perimeter of a shape is the sum of all the side-lengths of said shape. Because the shape is a rectangle, there are 4 sides (2 sides being the length, 2 sides being the width). This being said, the equation that can be used to find the perimeter is Perimeter = Length + Length + Width + Width or Perimeter = 2Length + 2Width. You would then plug in your given variables and solve for width. I have shown my work in the image below, I hope this is helpful :)
