Gerald purchased a rectangular plot of land. The length of the plot is 20 feet more than the width. The cost of the land was $ 12 per square foot . Gerald also had a fence put around the entire perimeter of the plot, at a cost of $8 per linear foot. The total amount he spent on both the land and the fence was $10,560 Part A Write an equation in two variables for the perimeter , and an equation in two variables for the area, A, of the plot of land where x is the width of the plot in feet. Provide evidence to support your equations . Part B Write an equation in one variable that can be used to find the width, x feet, of the plot. Express the equation in the form a * x ^ 2 + bx + c = 0 0. Provide evidence to support your answer . Part What are the dimensions , in feet, of the plot? Provide evidence , including an explanation of each step in the solution to the quadratic equation , to support your answer .
