Answer - 6 sq.units
Solution - As the triangle ADC is the reflection of the triangle ABC, so the area of both the triangles will be same.
Here BE is the height and AC is the base of ABC.
Area of triangle ABC = [tex]\frac{1}{2}[/tex]×Base×Height
= [tex]\frac{1}{2}[/tex]×3×4
= 6 sq.units
So the area of triangle ADC = 6 sq.units
