(Q2)Let A(x1 , y1) , B(x2 , y2) , C(x3 , y3) be three points. Then find the area of the following triangle and discuss with your friends in groups about the area of that triangle.

XX'YY'ABC

Given △AOB where A(x1 , y1) , B(x2 , y2) and C(x3 , y3)

But we know that the origin o is (0,0)

which is given as C

CB = x2 - x3 = x2 - = 2

AB = y1 - y2 = y1 - = 1

Area of △ABC =
