**Graham**, Tuesday, October 1, 2013 at 4:06amI cannot see the diagram, so I am going to assume the new fencing is formed into an 'E' shape, with the opening pressed up against the existing fence line. That is: one long side (l), two short sides and the divider (3w).

The fence length is:

800 = 3w + l

So the area is :

A = l w

A = 800 w - 3 w^{2}

The maximum area will be the value of the vertex of this parabola. Find w of this point.
