The largest area obtains when it's a square and that area is: *: 100%3 1111.11
i.e. the length of the barn wall is 100%3 meters and so are the lengths of the other 3 sides. Exercise for the reader: What is the largest area that can be enclosed with 100 meters of fence and one side of the barn, if the area can be of any shape? What is that shape?
