Let w represent the width of the rectangular garden, in feet. Since the length of the garden will be 5 feet longer than the width of the garden, the length of the garden will be w+5 feet. Thus the area of the garden will be w(w+5).It is also given that the area of the garden will be 104 square feet. Therefore, w(w+5)=104, which is equivalent to w2+5w−104=0. The quadratic formula can be used or the equation above can be factored to result in (w+13)(w−8)=0. Therefore, w=8 and w=−13. Because width cannot be negative, the width of the garden must be 8 feet. This means the length of the garden must be 8+5=13 feet.
