how to find the area of a triangle

#this is the code to find the area of a parrelogram and triangle #change the numbers to select what height and base your shape is b = 3 #b is base h = 3 #h is height (middle) t = 5 #this is the base of the triangle i = 5 #and this is the height p = t*i #dont touch this print("this is the area of the parrelogram") print(b * h) m = input("do you want to calculate a triangle? (space before answer)") print(m) if m == " yes": print ("this is the area of the triangle that you inputed") print (p/2) else: print("ok")

first you should know these details about the triangle(for the area) - hight (center) and the base lenght now, mutiply the height by the base and divide it by '2' //code var base = 5 var height = 9 var ans = (base * height) / 2 console.log(ans)

area of triangle

import java.util.Scanner;

public class shw2point15 {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        System.out.println("Enter three points for a triangle:");

        double x1 = input.nextDouble();
        double y1 = input.nextDouble();
        double x2 = input.nextDouble();
        double y2 = input.nextDouble();
        double x3 = input.nextDouble();
        double y3 = input.nextDouble();


        double s = ((x1 + y1) + (x2 + y2) + (x3 + y3)) / 2;
        double area = Math.sqrt(s * (s - (x1 - y1)) * (s - (x2 - y2)) * (s - (x3 - y3)));



        System.out.println("The area of the triangle is " + area);
    }
}
