Question 1170906
.
<pre>

If the width is W (unknown now), then the length is  (3W - 6),

and your basic equation is


    W + (3W-6) = 44/2,   or


    W + 3W - 6 = 22

    4W         = 22 + 6 = 28

     W                  = 28/4 = 7.


<U>ANSWER</U>.  The width is 7 feet.  The length is  7*3-6 = 21-6 = 15 feet.


<U>CHECK</U>.  The perimeter is 2W + 2L = 2*7 + 2*15 = 14 + 30 = 44 feet, which is PRECISELY CORRECT.

Solved.
