**bobpursley**, Sunday, October 17, 2010 at 10:03pmarea= LW

but 2W+L=600

L= 600-2W

area= (600-2W)(w)

well, roots are w=0, and w=300 that is where area is zero. Since a parabola is described here, the max will occur halfway, or w=150. Solve for Area when w=150

Plot Area vs W and see if this is so. Use your graphing calculator.

**Tori**, Sunday, October 17, 2010 at 10:04pmI already know that the answer is 300 for the length and 150 for the width, giving a sq ft of 45,000. The only problem is i do not know how to get that answer.
