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!

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
