How many feet in a Square Acre of Land?

A question that I often receive from new land surveyors is  How many feet is a square acre?I am not quite sure why this stumps so many, but this is basically what I tell them with they ask.A square enclosing one acre is approximately 69.57 yards, or 208 feet 9 inches (63.61 metres) on a side.
