240 cm²

This one is pretty simple, the triangle that sits on the upper left side of the shape fits right where there is a missing triangle shape on the upper right side. So just simply add 5.5 and 6.5 to get the total height of the figure and multiply it by the width (20).

5.5 cm + 6.5 cm = 12 cm

                 ↓  

12cm × 20 cm = 240 cm²

Your answer is 240 cm²

Have a great day!
