andrew11 [14]

Answer:

Width = 18 feet

Length =  43 feet

Step-by-step explanation:

Width = x

Length = x +25

Perimeter = 122 feet

2 * (length + width) = 122

    2 * (x+25 + x) =122

          2x + 25 = 122/2

             2x +25 = 61

                   2x = 61-25

                     2x = 36

                       x = 36/2

                       x = 18 feet

Width = 18 feet

Length = 18 + 25 = 43 feet
