An acre is a square that measures 208.7ft on all sides.
Your property as given is a quadrilateral, meaning it doesn't conform to the rules of a square, rectangle, trapezoid, rhombus, or parallelogram. Because the shapes mentioned have specific properties, the area formulas are the same for all cases.
But because a quadrilateral can be anything else, there isn't a general formula.
If you could give just one more bit of information, such as the length of a diagonal, or the angle where one or more of the sides meet, the calculation can be completed!
