In the NFL, a football field is 200 feet longer than it is wide, and the area of the field is 57,600ft^2
What is the width of the field?
(Before you mess this up, the field is not 100 yards long. You must include the lengths of the end Zones.) (And hey wait a second! Before you mess it up now, notice the problem is in
FEET.)

Answer
160ft
Step-by-step explanation:
Let the width be x.
Then the length is (x+200)
The area of the field=57600
Area=length*width
x(x+200)=57600
x^2+200x-57600=0
x=-360 or x=160
