show the equation used for the solution.

The length of a rectangle is 2 in. more than twice its width. If the perimeter of the rectangle is 34 in., find the dimensions of the rectangle.

• 12 & 5 inches
  If width=w, then length=2w+2
  Perimeter=2(length+width)=2(2w+2+w)=34
  w=5, So length=2w+2=12
