A rectangular lot is to be enclosed with an area of 160x - x^2 .
Let x meters be the length of the field, express the perimeter of the field as a function of x.
~~~~~~~~~~~~~~~~~~~~~~~~~~~
If the area is and x is the length, then the width is = 160-x meters.
Therefore, the perimeter is
P = 2x + 2(*160-x) = 320 meters. ANSWER
