How many square feet equal 1 acre?

One acre is defined as a unit of area that is equal to 43,560 square feet. This measurement is often used in land and property contexts. The acre originated from the amount of land that could be plowed in one day with a yoke of oxen. To provide a clearer understanding, an acre is equivalent to a rectangle that is 66 feet wide and 660 feet long, which also sums up to 43,560 square feet. This knowledge is crucial for professionals involved in structural pest control, as understanding property sizes is necessary for pest management, land use planning, and regulatory compliance.
