There are 5280ft per mile, so setting that up as an equation, we get
5280ft=1mi
Now let's square both sides.
(5280ft)^2=(1mi)^2
27878400ft^2=mi^2
Hence, there are 27878400 sq.ft. in a square mile

one mile is 5280 feet long.
a square mile is one mile by one mile (all sides are one mile long)
to find the area or the number of square feet in a square mile
multiply the the length 5280 by 5280 and this equals the number
of square feet in a square mile = 27,878,400 square feet
