# Rust program to calculate the area of a triangle for a given base and height

Given base and height of a triangle, we have to calculate the area of a triangle using Rust program.
Submitted by Nidhi, on September 29, 2021

Problem Solution:

Here, we will read the base and height of the triangle from the user. Then we will calculate the area of the triangle and print the result.

Program/Source Code:

The source code to calculate the area of a triangle for a given base and height is given below. The given program is compiled and executed successfully.

```// Rust program to calculate the area of a
// triangle for a given base and height

use std::io;

fn main()
{
let mut height:f32 = 0.0;
let mut base:f32 = 0.0;
let mut area:f32= 0.0;

let mut input1 = String::new();
let mut input2 = String::new();

println!("Enter base: ");
base = input1.trim().parse().expect("Not a valid number");

println!("Enter height: ");
height = input2.trim().parse().expect("Not a valid number");

area=(base * height) / 2.0;

println!("Area of a triangle: {}", area);
}
```

Output:

```Enter base:
12
Enter height:
7
Area of a triangle: 42
```

Explanation:

Here, we read the base and height from the user. Then we calculated the area of the triangle and printed the result.
