Answer:

Length = 10 inches

width = 25 inches

Step-by-step explanation:

Let the length of the rectangle be X inches

width = (3x - 5) inches

 Perimeter of rectangle =  70 inches

     2 * ( l + b)   = 70

2 * ( x + 3x - 5) = 70

             4x - 5 = 70 / 2

             4x - 5 = 35

                    4x = 35 + 5

                    4x = 40

                       x = 40/4

                        x = 10

Length = 10 inches

width = 3x - 5 = 3*10 - 5 = 30- 5 =  25 inches
