Perimeter is the sum of all sides.
Perimeter = 26 in
Since a rectangle has four sides and two pairs are parallel, you have to multiply each side given by two.

(4 * 2) + (x * 2) = 26
8 + 2x = 26
Tranpose '8' to the other side.
2x = 26 - 8
2x = 18
x = 9

9 + 9 + 4 + 4 = 26

Let:
  P-perimeter of the rectangle
  l -Length of the rectangle
  w-Width of the rectangle.

  P=2w + 2l
  26=2(4) + 2l
     l=9 inches.  (ans.)
