What equals one acre of land in square feet?

One acre of land is defined as being equal to 43,560 square feet. This measurement is a standard unit used in land assessment and is significant in real estate for determining property size and value. Knowing that an acre consists of this number of square feet is crucial for real estate professionals, as it helps them provide accurate information to clients regarding parcel sizes, zoning, and land use.

The other options reflect measurements that are either far too small or not relevant to the calculation of land area. For instance, 36 and 12 square feet are much too small to represent an acre. Additionally, while 5,280 feet is the length of a mile, it does not pertain to the area in square feet, which is essential for land measurement. Understanding these basic measurements is foundational for anyone involved in real estate transactions.
