Tamara has 138 138​ feet of fencing to construct a rectangular area next to a house. Tamara will only need to fence three sides, because the fourth side will be the wall of the house. Lastly, Tamara wants the length of the enclosure (parallel to the house wall) to be 24 24​ feet more than four​ times the width. Using the variables l​ and w​ to represent the length and width of the enclosure, respectively, write a system of equations to describe this situation. Enter the equations below, separated by a comma. What is the length of the enclosure? What is the width of the enclosure?
