One online resource that I consulted says that the total area of the USA is 9,826,675 square kilometers. I'm not going to spend a lot of time trying to verify that ... I saw it on the internet,
so I know it must be true.
That number is equivalent to 105,773,000,000 square feet. (rounded)
if you have a square acre how many ft. across is it
18-ft x 11-ft = 198 square ft
56,212.85 sq. ft. for malls in the United States
221 square feet
There are 324 square feet
960 square feet.
100-ft x 200-ft = 20,000 square feet
11 * 16 = 176 square feet
87.75 square inches

1,747 square ft = 0.04 acres.
