Answer :


a, b, c are in G.P.

To find:

Area of the triangle formed by the line ax + by + c = 0 with the coordinates axes.


The point of intersection of the line ax + by + c = 0 with the coordinate axis are (–c/a,0) and (0,-c/b).

So, the vertices of the triangle are (0, 0),

Let A be the area of the required triangle.



It is given that a, b and c are in GP.

b2 = ac


Hence, area A
