Question 123726
Given :

 Length is 5 inches more than width
 Perimeter is 70 inches

Assume Wdith  W = x
       Length becomes L = 5 + x
       Perimeter of a rectangle P = 2 (l + W)
                                 = 2 ( 5 + x + x)
                                 = 2 ( 5 + 2x)
                         70 = 10 + 4x
                         60 = 4x
                      then x = 15 ========> width = 15 inches
                       Length = 5 + x = 5 + 15  =   20 inches
