Question

If X1 X2 X3 are in AP with common difference d1 and y1 y2 y3 are in another AP with common difference d2 then area of the triangle formed by the point (x1 y1), (x2 y2), (x3 y3) is

Answer 1

Answer:

Cannot find because no triangle is formed!!!

Concept using:

Three or more points are collinear if and only if the corresponding coordinates are in AP.

Reason:

Given that x1, x2 and x3 are in AP and so are y1, y2, y3. As the corresponding coordinates are in AP, then the points (x1, y1), (x2, y2) and (x3, y3) are collinear. So no triangle is formed in joining them.
