Math Focus: Yet to find out.
Are you sure the software used to produce that doesn't have a function for calculating the area?

You can't calculate the area of such a figure just from the side lengths. You could, for example, take any three consecutive points and "flip" the middle point over the straight line between the other two points, changing "concave" to "convex" and vice-versa. That would change the area of the figure without changing side length. You need to know the angles as well.
Thanks from Denis
