find the area of a rectangle in go

To find the area of a rectangle in Go, you need to multiply its length by its width. Here's an example code block that demonstrates how to calculate the area of a rectangle in Go:

main.go
package main

import "fmt"

func main() {
    var length float64 = 5
    var width float64 = 3

    var area float64 = length * width

    fmt.Printf("Area of rectangle: %f units", area)
}

In this code, we first declare the length and width of the rectangle as float64 variables. We then calculate the area by multiplying the length and width together and storing the result in a new float64 variable area. Finally, we print out the area using the Printf function from the fmt package.
