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?

• math -

Is the fencing on all sides,or just three?

If three sides:
24=2L+w
Area=Lw=l(24-2L)

Using calculus, set the derivative to zero.
0=24-2L -2L
solve for L.Then go back and solve for W from the perimeter.
