Cindy has 500 feet of fencing to build a rectangular enclosure for her chickens. The enclosure has a a width of a feet a length of b feet an the perimeter is represented by the equation 2(a+b)=500. Part A suppose Cindy changes the width of the rectangular enclosure. Solve the equation for b to see how the new length will be affected. Show work Part B Cindy changes her mind and decides to purchase an additional 150feet of fencing. Instead of changing the width she instead wants to see how the width is affected by changing the length. Solve the equation for a and show work. Part C explain how to solve an equation for a particular variable if the equation consists of mostly variables and very few or no numbers.
