Question

Write a function that takes the base and height of a triangle and return its area.

Answer 1

Answer:

    //Method/function name is areaOfTriangle

    //Return type is double

    //Method receives two parameters of type double - base and height

    public static double areaOfTriangle(double base, double height){

        //Find the area using the formula: 1/2 * base * height

        double area = 0.5 * base * height;

       

        //return the area

        return area;

       

   } //End of areaOfTriangle method

Step-by-step explanation:

The function above has been written in Java.

It contains comments explaining each line of the code. Please go through the comments.

In order to test the function, a complete program containing a main method has also been written. This is shown as follows;

//Class definition begins

public class Area{

       

    //Method/function name is areaOfTriangle

    //Return type is double

    //Method receives two parameters of type double - base and height

    public static double areaOfTriangle(double base, double height){

        //Find the area using the formula: 1/2 * base * height

        double area = 0.5 * base * height;

       

        //return the area

        return area;

       

    }  //End of areaOfTriangle method

   

   

    //Write the main method to call the method

    public static void main(String []args){

       

       //Call the areaOfTriangle() method in the main method

       //Set the base to 12 and the height to 6

       System.out.println(areaOfTriangle(12, 6));

    }

   

   

} //End of class definition
