You'll need to find the radius
The circle track is 440 yards long. This is the circumference. Circumference = 2 X pi X radius
Radius therefore = 1/2 X Circumference/pi
(pi approx = 3.14)
Once you have the radius then you can find the area.
Area = pi X radius^2

That's normally called a "football field" hoss. A 1/4 mile (440 yd.) track is what you have around every high school football field I've ever seen. Since the field is normally 50 yards by 100 yards plus about 20 yards for each of two end zones that and about 10 yards for each sideline that should be about 140 yards by about 70 yards or about 9800 square yards of sod. I suppose your teacher wants you to figure the area inside the elliptical track so they probably want to see your work plus an exact answer. Hit the books.
