What percentage of the total land area is available for mans use, living and agriculture/farming?

A. 9.38%
*B. 3.13%
*C. 12.51%
D. 75%

I'm not sure if it is B or C.

Thank You.

I couldn't find this answer. It's an ambiguous question because some land can be used for farming if it is irrigated thoroughly. Also, does that include terrace farming on steep hillsides.

Go with whatever your book says.

To find the correct answer, we need to calculate the percentage of the total land area that is available for human use, living, and agriculture/farming.

First, we need to determine the total land area. The total land area of the Earth is approximately 148.94 million square kilometers (source: United Nations).

Next, we need to find the available land area for human use, living, and agriculture/farming. This includes areas such as cities, towns, residential areas, and farmland.

According to the United Nations, approximately 12% of the Earth's land area is classified as arable land, suitable for agriculture.

However, not all arable land is used for farming, as there are also other areas used for human settlements.

To estimate the total land area available for human use, living, and agriculture/farming, let's assume that around 75% of arable land is used for farming and the remaining 25% is dedicated to human settlements. This is a rough estimate, as the distribution may vary across different regions.

Now, let's calculate the percentage.

Percentage of land area available for human use, living, and agriculture/farming = (Arable land for farming + Land for human settlements) / Total land area

= (0.75 * 0.12 + 0.25 * 0.12) * 100

= (0.09 + 0.03) * 100

= 0.12 * 100

= 12%

Therefore, the correct answer is option C. 12.51%.
