Final answer:
The size of a lot that is ¼ of a mile wide by ¼ of a mile long is 40 acres.
Step-by-step explanation:
The question asks for the size of a lot that is ¼ of a mile wide by ¼ of a mile long. To find the area of the lot, we will multiply the width and the length together. Since the area of a full square mile is 640 acres, a quarter of a mile by a quarter of a mile would be ¼ times ¼ of 640 acres. This calculation is as follows: ¼ × ¼ × 640 acres = ⅔ × 640 acres = 160 acres. Therefore, the size of the lot is 160 acres, which is then divided by four to account for each quarter, giving us 40 acres per quarter-section.
Correct answer: B) 40 acres
