Question 1188329
.
A rectangle has a length 15 inches less than 5 times its width. 
If the area of the rectangle is 2750 square inches, find the length.
~~~~~~~~~~~~~~~


<pre>
Let w be the width; then the length is  (5w - 15) ft

The area equation is

    
    w*(5W-15) = 2750,

or

    w*(w-3) = 550  (after dividing both sides by 5).


You may solve this quadratic equation in a way you want,

or simply GUESS its solution mentally:  w = 25 ft.


So, the width is 25 ft;  the length is  5*25 - 15 = 110 ft.    <U>ANSWER</U>


<U>CHECK</U>.  25*110 = 2750 sq. feet,  the total area.   ! Correct !
</pre>

Solved.
