Solution

The correct option is A 12(c×d) sq. units

For the ΔABC, we have AB=a;BC=b;CA=c & d is the perpendicular from the vertex B.
Now, we know that the area of a triangle =12× Base× Height.
Now, here we have to select the appropriate Base and Height for the triangle.
Here, the perpendicular drawn on AC from the vertex B has a length d.
Correspondingly the Base will be AC
The area of the ΔABC
=12×d×c sq. units
