"The area of" is important there. If you're going by what wikipedia says, perhaps you could keep reading to the part where it also says "As a unit of measure, an acre has no prescribed shape; any area of 43,560 square feet is an acre."

Right but when someone specifically says 'width' for acre then what do you do? Assume they mean the width of a traditional acre, or claim you have no idea what they mean?

Well in this case they're apparently talking about something that has 2200 acres area, not widths-worth.
