76. Which of the following formulas is used to determine the number of acres in a parcel of land?
Answer: D
The formula used to determine the number of acres in a parcel of land is square feet divided by 43,560.
To calculate the number of acres in a parcel of land, the correct formula is to divide the total square footage by 43,560, since one acre is equivalent to 43,560 square feet.
A) length × width
This option describes the formula for calculating the area of a rectangular parcel of land in square feet, but it does not directly convert that area into acres. While length multiplied by width can give the total area, it does not provide the number of acres without further calculation.
B) square feet divided by 640
This formula is used to convert square feet into square miles, as there are 640 acres in a square mile. Therefore, this option is incorrect for determining the number of acres directly from square feet.
C) square miles × 1,296
This option appears to be incorrect because it does not relate to the conversion of square feet to acres. The calculation of square miles multiplied by 1,296 does not provide a meaningful conversion to acres, as the relationship is not mathematically accurate in this context.
D) square feet divided by 43,560
This is the correct formula to determine the number of acres in a parcel of land. Since one acre is defined as 43,560 square feet, dividing the total square footage by this number will yield the acreage.
Conclusion
The correct answer is D, as it accurately reflects the standard calculation for converting square feet into acres, which is essential in land measurement. Options A, B, and C fail to provide the necessary formula for determining the number of acres, highlighting the importance of using the correct conversion factor in land area calculations.
