Build a fence (I picked the size) 30ft x 50ft. 1. Define the area by establishing a relationship between the length and width of the rectangle. For example, L=2w+5 or w=3L-4. 2. Using the fact A=LW, together with the relationship mentioned in #1, eliminate one of the variables to set up a quadratic equation. 3. Solve the quad equation sing any of the techniques, the solution (s) will be one of the dimensions: use step in #1 to find the other.
