I have a question about geometry for homework. My problem is: "A rectangle with a perimeter of 64 inches has one side that is 4 inches shorter than the other. What are the dimensions of the rectangle?"
I don't know how to solve it but this is what I tried:
64 divided by 4 = x
I don't think this is right, please help me.

Question 171903: 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,
Kim
