Find the area of the following shape

12 i think

Step-by-step explanation:

because i add all the whole ones up and the ones that are cut in half there are 6 cut in half so you put two together and you should get 3 wholes and then you add the 9 to the 3 and you should get 12.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
