Final answer:
To find the percentage of the U.S. land used for work production, divide the production area of 650,000 square miles by the total area of 3.794 million square miles, then multiply by 100. It is approximately 17.132%.
Step-by-step explanation:
The question asks what percentage of the United States land area is used for work production if the total area is 3.794 million square miles and the area used for work production is 650,000 square miles. To calculate this percentage, we use the formula:
Percentage = (Part / Whole) × 100
In this case:
Part = 650,000 square miles
Whole = 3,794,000 square miles
We will follow these steps:
Divide the part by the whole: 650,000 / 3,794,000 = 0.17132
Multiply the result by 100 to find the percentage: 0.17132 × 100 = 17.132%
Therefore, approximately 17.132% of the United States land area is used for work production.
