I need to show how this problem is solved, and other than using addition (I think) I don't know how to solve it. Thank you very much for your time.

---------------------
Draw a rectangle.
Let the width be 6.
Let the length be "L".
Perimeter is 46
-----
Equation:
P = 2(L + 6)
46 = 2L + 12
2L = 34
Length = 17 inches
