<em>Answer:</em>
<h2>80</h2><em>Step-by-step explanation:</em>
The fastest and simplest way I got it is this...
There are 9 small squares that make up one big square, right?
The 5 out of 9 squares are shaded.
The area of the whole square is 144 (12 times 12).
The logical thing to do is figure out what's 5/9 (five-ninths) of 144.
So I believe the answer is 80.
Hope that helped! Tell me if it did, I don't want to mislead people. (So can I have brainliest?)
