How long and how wide is an acre in feet?

An acre is a measurement of land, so there is no defined shape. However, going back thousands of years when we were all farmers. A traditional Acre was long and narrow; reduced the number of times the plough had to be turned. A traditional Acre was a Furlong; meaning Furrows length (220 Yards or 660 Feet) long by a Chain (22 Yards or 66 Feet) wide. So 1 square Furlong (todays' city block) is 10 Acres. 8 Furlongs to a Mile. An Acre is 43,560 square feet. Acre comes from the old English word meaning "open field."
