How many acres are in a tract of land that measures 200 feet wide and 4000 feet deep?

To determine the number of acres in a tract of land that measures 200 feet wide and 4000 feet deep, first, calculate the total area in square feet.

The area can be found using the formula for the area of a rectangle, which is width multiplied by depth. Here, the width is 200 feet and the depth is 4000 feet, so:

Area = 200 feet × 4000 feet = 800,000 square feet.

Next, to convert square feet into acres, it is important to know that one acre is equal to 43,560 square feet. Therefore, you can find the number of acres by dividing the total area in square feet by the number of square feet in an acre:

Number of acres = 800,000 square feet ÷ 43,560 square feet/acre ≈ 18.365 acres.

This calculation confirms that the tract of land measures approximately 18.365 acres, making it the correct answer. Understanding the relationship between square feet and acres, as well as performing the necessary conversions, is essential for land measurement in real estate and appraisal practices.
