To find the area of the polygon, we need to know the shape of the polygon. If the polygon is a triangle, we can use Heron's formula or the formula A = (1/2) * base * height to find the area.

If the polygon is a quadrilateral, we can divide it into two triangles and calculate the area of each triangle separately.

If the polygon is irregular, we would need more information in order to calculate the area.

Please provide additional information or clarify the shape of the polygon so that we can calculate the area accurately.
