The total land available in the US = 3.794 million square miles which is 3,794,000 square miles
The land used for food production is 650, 000 square miles
To find the percentage used in food production, we divide the land used in food production by the total land and multiply the quotient by 100.
Percent for food =
(650, 000/3, 794, 000) * 100
Percentages land used for food
= 17.13%
