If land measures 400 by 3,275 feet, how many acres does it contain?

To determine how many acres the land measures, you first need to calculate the total square footage of the land. The area can be found by multiplying the length by the width. In this case:

400 feet (width) x 3,275 feet (length) = 1,310,000 square feet.

Next, to convert square feet to acres, you use the conversion factor that 1 acre is equivalent to 43,560 square feet. Therefore, you divide the total square footage by the number of square feet in an acre:

1,310,000 square feet ÷ 43,560 square feet per acre ≈ 30.07 acres.

This computation confirms that the area of the land is approximately 30.07 acres. This figure falls within the expected range for areas of this size, and the method used is consistent for calculating acreage from measurements in feet, which is widely accepted.
