Answer:
6660 yards^2
Explanation:
Assumption: the field is 120 yards long and 50 yards wide.
First calculate the area of the field: 120*50 = 6000 yards^2
Then, calculate the 11% of that area: 6000 yards^2*11/100 = 660 yards^2
Finally, the area of the tarp material should be 6000 yards^2 + 660 yards^2 = 6660 yards^2
