    Default Is anyone good with math?

    I am trying to help my DS with his math homework. We are stuck on one question. I am wondering if anyone would be willing to explain how to obtain the answer to us.

    "You are designing a rectangular enclosure with 8 rectangular sections separated by parallel walls. If you have 2900 feet of fencing, what is the maximum area that can be enclosed?"

    To fully answer the problem would require a whole lot of explanation and a couple of diagrams. Instead, I've sent you a PM with a link that will take you to a site which explains it pretty well. I'd link it here, but that's against the rules.

    Basically, you need to find the vertex of the graph of the quadratic equation 9X + 2Y = 2900. That will give you the values for X & Y that result in the maximum area.
