Question 1066265: I have 24 feet of fencing with which to build a rectangular rabbit pen to keep rabbits.
If I want the rabbits to have as much room as possible, how long would each of the sides be?
How long would each side be if I had only 16 feet of fencing?
How would you determine the pen with the most room for any amount of fencing?

~~~~~~~~~~~~~~~
A rectangle with the fixed perimeter which has the maximal area is a square.


Therefore, for the first case (24 feet of fencing) the maximal area is provided by a square with the side measure 
           of 24%2F4 = 6 ft and the area of 36 ft^2. 


For the second case (16 feet fencing) the maximal area is provided by a square with the side measure 
          of 16%2F4 = 4 ft and the area of 16 ft^2. 


For the third case/question, take the length of the fencing, divide it by 4 and get the side measure 
          of the square, which will give you the maximal area.

All question are answered.
