.
<pre>
154 = 11*14 is the decomposition of the number 154 into the product of two factors that differ by 3:  14 - 11 = 3.


Therefore, the dimensions of the room are  11 by 14 feet.


Alternatively, you can find these dimensions by solving quadratic equation


    x*(x+3) = 154.


Having dimensions, you can easily find the perimeter.


<U>Answer</U>.  11 + 14 + 11 + 14 = 50  feet.
