Question 1185620
.
A rectangular field has a perimeter of 194 feet. The length is 7 feet more than four times the width.
What is the length and what is the width?
~~~~~~~~~~~~~~


<pre>
W = width

L = 4W + 7   (the length)


Equation


    W + (4W + 7) = 194/2

   
    5W + 7 = 97

    5W     = 97 - 7

    5W     = 90

     W     = 90/5 = 18.


<U>ANSWER</U>.  The width is 18 feet;  the length is  4*18 + 7 = 79 feet.


<U>CHECK</U>.  18 + 79 + 18 + 79 = 194 feet, the perimeter.    ! Correct !
