Question 1158262
.
The area A, in square meters, of a {{{highlight(cross(crectangle))}}} <U>rectangle</U> with a perimeter of 160 meters 
is given by the equation A = 80w - w squared, where w is the width of the rectangle in meters. 
What is the width of a rectangle if its area is 700 m squared?
~~~~~~~~~~~~~~~~



<pre>
Solve this quadratic equation

    80w - w^2 = 700,



Solve it by factoring

    w^2 - 80w + 700 = 0

    (w-10)*(w-70) = 0.



<U>ANSWER</U>.  The dimensions of the rectangle are 10 meters by 70 meters,
         giving the width, as a smaller dimension, 10 meters.

Solved.
