Vitaly and Jen have 24m of fencing to enclose a vegetable garden at the back of their house. What are the dimensions of the largest rectangular garden they could enclose with this length of fencing?

Is the fencing on all sides,or just three?
If three sides:
24=2L+w
Area=Lw=l(242L)
Using calculus, set the derivative to zero.
0=242L 2L
solve for L.Then go back and solve for W from the perimeter. 
yeah, its 3 sides thanks
