Here, we will read base1, base2, the height of Trapezium from the user. Then we will calculate the area of the Trapezium and print the result.

Area of Trapezium formula = h/2(b1+b2)

Where h is the height, b1 is the base1, and b2 is the base2.

Program/Source Code:

The source code to calculate the area of Trapezium is given below. The given program is compiled and executed successfully.

// Rust program to calculate the 
// area of Trapezium

use std::io;

fn main() 
{
    let mut base1:f32 = 0.0;
    let mut base2:f32 = 0.0;
    let mut height:f32 = 0.0;
    let mut area:f32 = 0.0;
    
    let mut input1 = String::new();
    let mut input2 = String::new();
    let mut input3 = String::new();
       
    println!("Enter base1: ");
    io::stdin().read_line(&mut input1).expect("Not a valid string");
    base1 = input1.trim().parse().expect("Not a valid number");
    
    println!("Enter base2: ");
    io::stdin().read_line(&mut input2).expect("Not a valid string");
    base2 = input2.trim().parse().expect("Not a valid number");

    println!("Enter height: ");
    io::stdin().read_line(&mut input3).expect("Not a valid string");
    height = input3.trim().parse().expect("Not a valid number");
    
    area = 0.5 * (base1 + base2) * height;
    
    println!("Area of Trapezium is: {}", area);
}

Output:

Enter base1: 
3
Enter base2: 
4
Enter height: 
1
Area of Trapezium is: 3.5

Explanation:

Here, we read the value of base1, base2, and height from the user. Then we calculated the area of the Trapezium and printed the result.
