Find the Area of a Triangle Using coordinates

Objective – Given three vertices coordinates or (X, Y) coordinates, write a program to find the area of a triangle.



Given the coordinates of the three vertices of any triangle are (X1, Y1), (X2, Y2) and (X3, Y3)

Java Code:

public class AreaOfTriangleCoordinates {
public static void printArea(double [] X, double [] Y){
//find area of triangle
double area = Math.abs(X[0]*(Y[1]-Y[2]) + X[1]*(Y[2]-Y[0]) + X[2]*(Y[0]-Y[1]))/2;
System.out.println("Area of Triangle: " + area);
public static void main(String[] args) {
double [] x_coordinates = {1,2,5};
double [] y_coordinates = {0, 6, 10};
printArea(x_coordinates, y_coordinates);


Area of Triangle: 7.0
