how many square feet is a football
This implies, the dimensions of a soccer field are: 54,000 sq.ft - 86,400 sq.ft. A Google search yields 100 yards long by 60 yards wide for a regulation soccer field for adults. Going with this info, this translates to 300 feet long by 180 feet wide. The area in square feet is therefore 300 times 180, or 54,000 square feet. Based on the other answers given, this is probably on the low end of the range of soccer fields in use, regulation or otherwise.
