The area of a rectangular region is increasing at a rate of 250 square feet per

Choice A is correct. It’s given that $1 \text{meter}=3.28 \text{feet}$. It follows that $1^2 \text{square meter}={3.28}^2 \text{square feet}$, or $1 \text{square meter}=10.7584 \text{square feet}$. Since $1 \text{hour}=60 \text{minutes}$, it follows that $250$ square feet per hour is equivalent to $\left(\frac{250 \text{square feet}}{1 \text{hour}}\right)\left(\frac{1 \text{square meter}}{10.7584 \text{square feet}}\right)\left(\frac{1 \text{hour}}{60 \text{minutes}}\right)$, or $\frac{250 \text{square meters}}{645.504 \text{minutes}}$, which is approximately $0.3873$ square meters per minute. Of the given choices, $0.39$ is closest to $0.3873$.

Choice B is incorrect and may result from conceptual or calculation errors.

Choice C is incorrect and may result from conceptual or calculation errors.
