&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>MENTAL &nbsp;&nbsp;SOLUTION</U>



<pre>
Let the width be w feet; then the length is  (2w-5) feet.


The equation for the area is


    w*(2w-5) = 75.


Double both sides


    2w*(2w-5) = 150.


Two numbers that give the product 150 and differ in 5 units are 10 and 15.


So, 2w = 15;  hence, w = 7.5.


<U>ANSWER</U>.  The width is 7.5 ft;  the length is 2*7.5-5 = 10 ft.

Solved.
