Solve the following problems. Show your complete solution.
1. A two-pen corral is to be build. The outline of the coral forms two identical adjoining rectangular regions. That is 120 feet of fencing available.
Find the maximum enclosed area and the dimensions of the corresponding enclosure.
2. Suppose a wire three feet log is to be cut into two pieces, with each piece to be formed into a square. Find the size of each piece to maximize
the area of the two squares.
3. Out of frustration, Maxine throws a stone into a river. This caused ripples in the form of concentric circles. The radius of the outer ripple
increases constantly at 2 feet per second. At what rate is the total area of the disturbed water changing when the radius is 5 feet?
