find the area of a rectangle in rust

To find the area of a rectangle in Rust, you need to define the variables for its length and width, and then multiply them together to get the area.

main.rs
fn main() {
    let length = 5; // define length of rectangle
    let width = 10; // define width of rectangle
    let area = length * width; // multiply length and width to get area
    println!("The area of the rectangle is {}", area); // print the result
}

In the code above, we define the variables length and width as integers with the values 5 and 10 respectively. Then we create a new variable called area, which is assigned the value of length multiplied by width.

Finally, we print out the result using Rust's println! macro. The output will be: The area of the rectangle is 50.
