The answer is the second option: [tex]12(6+3)[/tex]
The explanation is shown below:
1. To solve and expression by applying the Distributive property, this expression must have the following form:
[tex]a(b+c)[/tex]
2. As you can see in the figure attached, the second option has that form. Therefore, that is the rigth option.
3. You can solve it as following:
[tex]12(6+3)=(12)(6)+(12)(3)=72+36=108[/tex]
Which is the total area.
