Part One
1. You are employed by Fences R Us, an aluminum fencing company that specializes in building fenced enclosures. Your job is to build these enclosures on your client�s properties. One client has purchased a certain length of fencing and wants to enclose the largest possible area in her yard. All gates are included in the fencing.
a. Suppose that the client needs 100 feet of fencing. Choose several values for the width of the rectangle and determine the corresponding lengths and areas of the rectangle.
Width (in feet) Length (in feet) Area (in sq. feet)
20� 30� 600sq �
10� 40� 400sq�
35� 15� 525sq�
25� 25� 625sq�
What is the relationship between the length and width of rectangles with a perimeter of 100 feet?
p=2 (l + w)

So, the perimeter is 100 feet
b. Determine whether there is a rectangle enclosed by 100 feet of fencing that has the following areas:
� 400 square feet h x w=a 10*40=400
� 500 square feet h * w = a
� 700 square feet
c. Let c represent the length of a rectangle enclosed by 100 feet of fencing. Write an expression for the width of the rectangle in terms of c.
d. Express the area A of a rectangle with perimeter 100 feet as a function of the length c of one of its sides.
e. Simplify this function so that it reads as a quadratic equation.
2. If you were to sketch the graph of the function in 1e, where the x-axis is labeled as your length (in feet) and the y-axis is labeled as your area (in square feet), you will see that it has the shape of a parabola.
� Use the graph to determine the dimensions of a rectangle with perimeter 100 feet and the following two areas:
o 400 square feet & 500 square feet
� Explain how 700 square feet is not a possible area in this situation.

3. Use the function in 1e to algebraically determine the length c of a rectangle with perimeter 100 feet. and the following areas:
� 400 square feet

� 500 square feet

4. Use the function in 1e to algebraically support the conclusion that 700 square feet is not a possible area in this situation.

5. What is the maximum value of the function in 1e? Explain how you arrived at this conclusion and what does the maximum value represent.

6. What is the corresponding length c of the rectangle? Explain how you arrived at this conclusion.

7. What is the most specific name for the rectangle with perimeter 100 feet and length c found in #6?
