Who is asking: Parent Question: 

Hi, I would draw a diagram. This is the diagram I drew. I need to put some labels on the diagram so that I can tell you how it helped me solve the problem. Since the corral is 40 feet longer than it is wide I put a point E on the side AB so that the length of AE is the same as the length AD. Thus the length of BE is 40 feet. In a similar fashion I put the point F on CD so that the length of CF is 40 feet. Thus the lengths of AE, BC, FD and AD are all the same. If I just knew that length I would know the perimeter. To set up an equation let this unknown length be x feet. Then I know that
Thus
Now solve for x, which is the width of the corral. Cheers,
