w = width

L= length = 51 + w        given

 

perimeter =   w + w + l+ l =     2 w    + 2(51+w)   = 146      solve for w, then l = w+ 51

The length of a rectangle is 51 inches more than the width. The perimeter is 146 inches. Find the length and the width.

 

146 - 102 = 44       44 / 4 = 11

The width is  11 in

The length is    (146 - 22) / 2 = 62 in  indecision
