Answer:

12 square feet.

Step-by-step explanation:

The formula for the area of a triangle is A = [tex]\frac{l*w}{2}[/tex]

So if you multiply 3 by 4 you get 12 then divide it by 2, which equals 6. Then you do the same with the second triangle, (3*4)/2 = 6. Now if you add the two areas you get 12 square feet.
