The length is 9.
The formula to find the perimeter of a rectangle is
2L + 2W = P.
2L + 2(4) = 26.
2L + 8 = 26.
2L + 8 (-8) = 26 (-8).
2L = 18.
2L/2 = 18/2.
L = 9.
This is the "commutative property of addition." The order in which you add numbers together doesn't matter, and doesn't change your final results.
