It is given that in △ABC, AD ⊥ BC. Using the definition of sine with angle C in △ACD results in sin(C) = StartFraction h Over b EndFraction. Using the multiplication property of equality to isolate h, the equation becomes bsin(C) = h. Knowing that the formula for the area of a triangle is A = One-halfbh is and using the side lengths as shown in the diagram, which expression represents the area of △ABC?
