Question 171903This question is from textbook Algebra & Trigonometry
: This problem is in the review section about the farmer and fencing.
A farmer with 10,000 meters of fencing wants to enclose a rectangular field and then divide it into two plots with a fence parallel to one of the sided. What is the largest area that can be enclosed?

I really have no clue even where to start by solving this problem, I have searched it and found that we need to maximize the area by using a formula that looks something like(2wx2L=?) but after applying it to my problem I came up with this formula (2Lx3W=10,000. I have no clue if I am even going in the right direction. I used the two lengths because we have two long sides, and 3 widths because there is also the dividing line of fence that has to be accounted for. Any help is appreciated.
Thanks,
KimThis question is from textbook Algebra & Trigonometry
