There was another forum about this, and my teacher said the answer was incorrect, so here.

In the figure, what is the area of triangle ABC ? Express your answer as a common fraction.

It's a right triangle so 

 

\(A = \dfrac{\ell_1 \ell_2}{2} = \dfrac{(2+2)(3+4)}{2}=\dfrac{28}{2}=14\)

 

are you sure the question isn't what's the area of triangle ABD?
