Next, let’s suppose a rancher wants to fence off a rectangular shaped enclosure that has two identical sections. You can think of this as a rectangle with an additional fence dividing the rectangle in half. For the sake of this question, he wants that additional fence running North-South (up-down). He still has 2400 feet of fencing that he can use. What are the dimensions that gives the enclosure the most area?

(a) Use the sketch of the pen below for this question. Appropriately label the relevant information in the sketch. Remember, East-West is right-left, North-South is up-down.

(b) Based on the sketch above, what equation is being maximized?

(d) Find the dimensions of the enclosure that gives the largest area.

(e) How much fence is used on the East-West sides? How much fence is used on the North-South sides? What is the ration of the amount of fence used on the East-West sides to the amount of fence used on the North-South sides?

2. A rancher has set out to fence off a new rectangular pasture for her horses. She has 1000 feet of fencing to fence off as large an area as possible. She wants to give the horses some water access, so she is building the pasture along a river, which will not need fencing. (a) Write a function, P(x), that describes the area of the pasture as a function of its length, x. (Don’t need Python for this.) (b) Plot...

As a farmer, suppose you want to fence off a rectangular field that borders a river. You wish to find out the dimensions of the field that occupies the largest area, if you have 1200 feet of fencing. Remember that a square maximizes area, so use a square in your work. Draw several diagrams to express the situation and calculate the area for each configuration, then estimate the dimension of largest possible field. Find the function that models the area...

Greg wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence on that side. The other three sides will be enclosed with wire fencing. If Greg has 650 feet of fencing, you can find the dimensions that maximize the area of the enclosure. a) Let WW be the width of the enclosure (perpendicular to the barn) and let LL be the length of the enclosure (parallel...

A farmer wants to fence in a rectangular plot of land adjacent to the north wall of his barn. No fencing is needed along the barn, and the fencing along the west side of the plot is shared with a neighbor who will split the cost of that portion of the fence. If the fencing costs $16 per linear foot to install and the farmer is not willing to spend more than $4000, find the dimensions for the plot that...
