A square foot (abbreviated as ft2) is a unit of area measurement equivalent to a square measuring 1 foot on every side. One square foot equals to approximately 0.09 square meters. A square foot is a unit of area used mostly in the imperial and U.S. customary measurement systems.
There are 27,878,400 square feet in a square mile. That is the correct amount because to find the area of something, one multiplys the length and width. So to find how many square feet are in a square mile, one must multiply 5,280(the amount of feet in a mile) times 5,280(the product is 27,878,400). I hope that answers your question :)
