Problem-fence in a rectangular area


Assignment:

Congratulations, you have just purchased your first house. Unfortunately, the builder forgot to put a fence around the property and you must now put a fence up so that you can let your pet out in the backyard, without fear of it running away.

(My pet would be a large dog such as a Mastiff).

You want to fence in a rectangular area, but first you must determine the dimensions of the area.

Q1. Different pets need to have different areas. For example, a horse needs more space than a dog. Determine an area that is appropriate for your pet.
Q2. Define the shape of the rectangular area by establishing a relationship between the length and width of the rectangle. For example, L = 2W + 5, or W = 3L - 4. Be sure to include the appropriate units (inches, feet, yards, miles, or meters).
Q3. Using the fact that A = LW, together with the relationship defined in step 2, eliminate one of the variables to set up a quadratic equation.
Q4. Solve the quadratic equation using any of the techniques learned in this unit. The solution(s) will be one of the dimensions; use step 2 to find the other.
Q5. Determine the perimeter so that you will know how much fencing to buy.

Your answer must be typed, double-spaced, Times New Roman font (size 12), one-inch margins on all sides, APA format.
