Question 242079
Hello, 
Once we've represented the width and length then we can set up an equation. 
Let x be the length and x-42 be the width. Now we can set up how it will look. 
x+x+(x-42)+(x-42)=220 Combine like terms, we get:
4x-84=220  Add 84 to both sides to get:
4x=304 Divide each side by 4 to result in:
x=76
Now we know the length is 76 yards and the width is 34 yards. To check it out, add these up. Remember there are 4 sides.
