Answer:
48cm^2
Explanation:
First, you can break down this shape into two different, easier to work with shapes, with dimensions of 4*9 and 6*2. You can get this by cutting the bigger rectangle into the 4*9, and then using the 6*2 left over.
After that, all you need to do it multiply and then add.
4*9 is 36, and 6*2 is 12.
36+12=48
