- To find the area of a triangle in a graph, you can12:
- Drag the origin point to move the axes.
- Click "hide details".
- Drag the triangle to some random new shape.
- Calculate its area and then click "show details" to see if you got it right.
- Estimate the area by counting the grid squares inside the triangle. (Each square is 5 by 5 so has an area of 25).
- Use the formula: area = Ax (By-Cy)+Bx (Ay-Cy)+Cx (By-Ay)/2 Ax = x coordinate for point A Ay = y coordinate for point A Bx = x coordinate for point B By = y coordinate for point B Cx = x coordinate for point C Cy = y coordinate for point C2.

Area of Triangle in Coordinate Geometry - Cuemath
The area of a triangle on a graph is calculated by the formula of area which is: A = (1/2) |x 1 (y 2 − y 3) + x 2 (y 3 − y 1) + x 3 (y 1 − y 2)|, where (x 1,y 1), (x 2,y 2), and (x 3,y 3) are the coordinates of vertices of triangle on the graph.
