If we have three points (x1,y1)(x2,y2),(x3,y3)
Then their area is 1/2[x1(y2-y3)+x2(y3-y1)+x3(y1-y2)]
Then their area is 1/2[x1(y2-y3)+x2(y3-y1)+x3(y1-y2)]

Hi !
Let the coordinates of the triangle be :-
A = (x₁,y₁)
B = (x₂,y₂)
C = (x₃,y₃)
Then ,
area of triangle ABC = 1/2*{ x₁(y₂ + y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)}
Hope this helps you !
