Aug 5, 2024 · Using the height and base of the triangle; Using the 3 sides of the triangle; Case 1: When the height and base of the triangle are given, then the area of the triangle is half the product of its base and height. Formula: Area of triangle: Area = (height×base)/2. Example 1: Evaluation of area using base and height Java

Feb 27, 2015 · They want you to have the user enter 6 coordinates (x and y value) for the 3 points of a triangle and get the area. My code is as follows: // find the area of a triangle. public static void main (String [] args) { double side1 = 0; double side2 = 0; double side3 = 0; Scanner input = new Scanner(System.in); //obtain three points for a triangle.

(Geometry: area of a triangle) Write a program that prompts the user to enter three points (x1, y1), (x2, y2), (x3, y3) of a triangle and displays its area. import java.util.Scanner;

Here is our complete Java program to find the area of a triangle given base and height or points of three vertices. I have created a Point class to represent a point that has both X and Y coordinates and two overloaded area() methods to calculate the area of a triangle.

Jan 25, 2016 · A compact and nicely symmetric way to remember the area formula is [ 1 a.x a.y ] area = 0.5*det[ 1 b.x b.y ] [ 1 c.x c.y ] This will give a signed area, negative if the order of the vertices is clockwise. For implementations one of course simplifies the determinant by row and column operations.

Write a Java Program to find the Area of a Triangle with an example. If we know the length of three sides of a triangle, we can calculate the area of a triangle using Heron’s Formula: Area of a Triangle = √(s*(s-a)*(s-b)*(s-c))

Mar 5, 2015 · According to the java.awt.point documentation, you should use the getX() and getY() methods, which return the coordinate value of a point. That is, Should be expressed as: (a.getX()-b.getX())*(c.getY()-a.getY()))*0.5;

* three points (x1, y1), (x2, y2), (x3, y3) of a triangle and displays its area. * The formula for computing the area of a triangle is * s = (side1 + side2 + side3)/2;

Mar 11, 2025 · Write a Java program to calculate the area of a triangle using the sine of an angle given two sides and the included angle. Write a Java program to compute the area of an equilateral triangle given its side length.

(Geometry: area of a triangle) Write a method for computing the area of a triangle using the following method: public static double getTriangleArea (Point p1, Point p2, Point p3) Write a program that prompts the user to enter three points of a triangle and displays the triangle’s area.
