Suppose a wire that is 107 feet long is cut into one piece of length x feet and another of length 
feet. The first piece is bent into a square, and the second is bent into a circle. The total area enclosed is given by
square feet.
A: Make a graph of A versus x. In choosing your viewing window, bear in mind that the formula makes sense only when x is between 0 and 107.B: What is the area at the left-hand endpoint? What physical situation does that represent? Round your answer to two decimal places, if necessary.C: What is the area at the right-hand endpoint? What physical situation does that represent? Round your answer to two decimal places, if necessary.D: How should the wire be used so that the maximum area is enclosed?
