Question 4 (1 point) An area has: 1,000 people 300 farmers 200 total sq. mi 30 sq. mi. of arable land Calculate the agricultural density. a \( \quad 1.5 / \mathrm{sq} . \mathrm{mi} \). b \( \quad 10 / \mathrm{sq} \cdot \mathrm{mi} \) c \( \quad 33.33 / \mathrm{sq} . \mathrm{mi} \) d

To calculate the agricultural density, we use the formula: \[ \text{Agricultural Density} = \frac{\text{Number of Farmers}}{\text{Arable Land in Square Miles}} \] So, substituting in the numbers: \[ \text{Agricultural Density} = \frac{300 \text{ farmers}}{30 \text{ sq. mi.}} = 10 \text{ farmers/sq. mi.} \] Thus, the answer is option **b \( \quad 10 / \mathrm{sq} \cdot \mathrm{mi} \)**. Agricultural density provides a useful indicator of how effectively land is used for farming in a given area! Higher agricultural density means more farmers per available arable land, which can indicate productive land use. Did you know that around the world, regions with high agricultural density can face challenges like land degradation and resource depletion? This makes sustainable farming practices essential to maintain productivity while preserving the environment!
