# Java program to enter the base and height of a triangle and find its area

ADVERTISEMENTS

Java program to enter the base and height of a triangle and find its area.

There are you will learn how to find the area of a triangle by using the base & height of the triangle in Java language.

**Formula:**

*a = (b + h) / 2*

**Where:**

*a = area*

*b = base*

*h = height*

Let us understand this example through the Java program:

```
// Java program to find the area of a triangle if base and height are given
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter the base & height of the triangle::\n");
float b = in.nextFloat();
float h = in.nextFloat();
float a;
// b = base
// h = height
// a = area
// Calculate area of the triangle
a = (float)((b * h) / 2);
// Output
System.out.println("\nArea of the triangle = " + a + " sq. units\n");
}
}
```

**Output:**

Enter the base & height of the triangle::

5

7

Area of the triangle = 17.5 sq. units
