Divide it into two squares.
The first square is just (1)1, which equals 1 cm^2, and add that to the second square, which is just (2)2, which equals 4, so 1+4=5 cm^2.
Here is your answer: Combine like terms: 4a+2a=6a and 8b-6b=2b Your answer is 6a+2b
The answer is 53. You just need to find the magnitude
