Your work is correct.
Yes. First find, , then set that equal to zero to find a critical point (a potentially optimized value for)
If you need further assistance, please provide your value for .
1) A rectangle study area is to be enclosed by a fence and divided into two equal parts, with a fence running along the division parallel to one of the sides. If the total area is 384ft^2, find the dimenstions of the study area that will minimize the total length of the fence. How much fence will be required?
let = total length of fence
someone told me to find and minimize
so do I just set this equation to 0 and ..?
