How many square yards in a square acre?
There are 4,840 square yards in an acre. However, the term "square acre" is incorrect. An acre, by definition, is a unit of area, and therefore the "square" prefix is unneccessary. Moreover, an acre is not generally thought of as "square" anyway, because there is no way you can posit a square acre using whole numbers for the lengths of the sides. An acres is 43,560 square feet. The square root of this number is approximately 208.7103. That would be the approximate length of the sides of your "square acre". Traditionally, an acre was defined as an area 660 feet (one furlong, or ten chains) long and 66 feet (one chain) wide. But an acre need not be this shape to be considered an acres. Any piece of land that is 43,560 square feet in area is considered an acre.
