Question

I don’t think this is correct but I got an area of 21.Can anyone help me or correct me on my error??

Answer 1

Cut the figure into 2 parts, like you already have here.
There are now two parts with the dimensions of 3 x 3 and 2 x 9.
Multiply 3 x 3. That is 9.
Multiply 9 x 2. That is 18.
Add together 18 and 9. That is 27.
The answer is B, 27 in².
Hope this helps!
