I guess you mean American football fields (base on use of "Fields" as opposed to "Pitches").
Assuming you mean the playing area including end zones, then:
The field is 360ft long x 160ft wide meaning the area of 2 of them is
area = 2 x 360ft x 160ft = 115,200ft2
1 mile = 5280ft, so 1 sq mile = 5280ft x 5280ft = 278,784,000ft2
So for 2 football fields
area = 115,200ft2
= 115200 ÷ 278784000 sq miles
~=0.0041 square miles.
400 sq. miles = 27,878,400 sq. ft. x 100 = 2,787,840,000 sq. ft.
If you're talking about length and not area, 52.8 football fields (end-zones excluded) will have a length of 3 miles.
Probably 12. (Most tracks around football fields are 440 meters = 1/4 mile).
250 square miles.
It round to: 59,420 square miles and not 59,419 square miles
1000
The Sahara is 9,000,000+ square kilometers or 3,300,000+ square miles which is millions of time greater than 30 football fields.
4,132,187 US, NFL fields would fit in that area.
15 miles = 264 American football fields.
56 American football fields is about 3.18 miles.
7,417 miles = 130,539.2 American football fields.
483,682,810 miles = 8,512,817,456 American football fields.
4,832 miles = 85,043.2 American football fields.
Well, a football field is 50 yards by 100 yards, so that is 5000 square yards.3.5 million square miles (5280 feet/1 mile)(1 yard/3 feet)= 6,160,000,000 yards square-------------------------------------------so,6,160,000,000 yrd2/5000 yrds2= 1,232,000 football fields====================
528 American football fields.
0.05 square miles is equivalent to 32 acres. This can also be visualized as approximately 26 football fields.
187,475.2 American football fields.
