- The shape for which I am trying to calculate the area is not a perfect ellipse. I can't paste a copy of its outline here. If a straight line is drawn across the length of the figure, from point to point, then there is less area above the line than below it. It could be described as a flattened ellipse. At the center point of the long dimension, it appears that the area below the line is about twice that above. The dimensions are 11.8 cm by 23.7 cm. This makes a=23.7/2=11.85 and b=11.8/2=5.9, if it were symmetrical. The vendor states an area of 200 sq cm. Your formula returns 219.64445... Any ideas as to how I can calculate the area of this figure? Thank you.
