What is the area of an acre expressed in square feet?

An acre is a unit of area commonly used in the United States to measure land. The standard measurement for one acre is precisely 43,560 square feet. This figure is derived from the historical definition of an acre, which was based on the amount of land that could be plowed by a yoke of oxen in one day.

Understanding that 43,560 square feet equals one acre is essential for landscape contractors, as they often need to calculate dimensions and volumes for landscaping projects, land development, and other construction-related activities. Knowing this measurement helps contractors develop accurate plans and estimates for materials and labor costs on various projects.

Thus, the correct choice reflects a fundamental metric that is integral to the field of landscaping and land management.
