Agronomy Degree Practice Exam

If a field is 0.5 miles long and 0.3 miles wide, what is its area in acres?

1. 96 acres

2. 75 acres

3. 45 acres

4. 100 acres

The correct answer is: 96 acres

To calculate the area of the field in acres, first determine the area in square miles and then convert it to acres. The area of a rectangle can be calculated using the formula: Area = Length × Width. In this case, the field is 0.5 miles long and 0.3 miles wide. Therefore: Area = 0.5 miles × 0.3 miles = 0.15 square miles. Now, to convert square miles to acres, one can use the conversion factor that 1 square mile is equal to 640 acres. Thus, you would multiply the area in square miles by 640: Area in acres = 0.15 square miles × 640 acres/square mile = 96 acres. This calculation shows that the area of the field is indeed 96 acres, making this the correct answer.
