It is an application that calculates the area. We will calculate the length of the area and some from the sides and angle triangle, square, regular polygons, circles, ellipses, pies, pies ellipse, arc, elliptical arc, or parabola. You can calculate the current 58 kinds of shapes. If you have any request, please fill in the comment. I will also want to add functionality as much as possible. Note: The length of the arc of the ellipse is determined by the integration because it takes a long time, there is a slight difference.
