To find the area of the shape with side lengths of 9 cm, 11 cm, 14 cm. and 20 cm, we need to determine the shape we are dealing with. From the aiven side lenaths, it is not clear what shape it is because there are multiple possibilities. One possibility is that the shape could be a trapezoid. In a trapezoid, the area can be calculated by using the formula: Area (1/2) * (sum of parallel sides)* height If we consider the side lenaths 9 cm and 11 cm as the parallel sides, we still need the height of the trapezoid to calculate the area. Another possibility is that the shape could be a quadrilateral. In a quadrilateral, the area can be calculated by dividing it into two triangles and adding their aretogether. To do this, we need to find the height of the quadrilateral, which is the perpendicular distance between the parallel sides. Without additional information such as the height or the angles of the shape, it is not possible to accurately determine the area. If you have any further information or any other details about the shape, please provide them, and I'll be able to assist vou in calculating the area more accurately.
