Which of the following formulas is used to determine the number of acres in a parcel of land?

Rationale

Square feet divided by 43,560 determines the number of acres in a parcel of land.

This formula is derived from the fact that one acre is defined as 43,560 square feet. By dividing the total area in square feet by this number, one can accurately convert the area into acres.

A (length × width) YOUR ANSWER

This choice represents the formula for calculating the area of a rectangular parcel of land in square feet. While this calculation is essential for determining total area, it does not directly provide the number of acres unless further processed using the appropriate conversion factor.

B (square feet divided by 640) YOUR ANSWER

Dividing square feet by 640 converts square feet into square miles, not acres. There are 640 acres in a square mile, but this calculation does not yield the desired result for converting to acres directly from square feet.

C (square miles × 1,296) YOUR ANSWER

This option suggests a conversion from square miles to another unit; however, it incorrectly applies the conversion factor. One square mile equals 640 acres, not 1,296, making this choice incorrect for determining the number of acres in a parcel of land.

Conclusion

The formula for calculating the number of acres from square feet is square feet divided by 43,560, as this correctly reflects the definition of an acre. Other choices either describe area calculations without conversion or misapply the necessary conversion factors, highlighting the importance of using the correct formula for accurate land area assessments.

Which of the following formulas is used to determine the number of acres in a parcel of land?

Square feet divided by 43,560 determines the number of acres in a parcel of land.
