Background: what to know before you rely on it
Land area has been measured by ancient units such as the acre, which began as the area a team of oxen could plough in a day. Metric countries use the hectare, defined as a square of 100 meters on each side. Real estate in some regions adds local units whose size varies by place. Because of this variation, written agreements should state the area in square feet or square meters.
