Go – Program to calculate area of Rectangle and Square

Here, We are going to write a program to calculate area of Rectangle and Square in go golang. Area of rectangle is multiplication of length and breadth i.e length * breadth whereas area of Square is square of length i.e length * length.


  • Get the length and breadth of rectangle
  • Calculate the area of rectangle by multiplying length and breadth
  • Calculate the area of square by squaring the length

Example with code:

package main
import "fmt"
func main(){

  var length, breadth = 3, 4

  var area int

  area = length * breadth

  fmt.Println("Area of Rectangle : ", area)
  area = length * length

  fmt.Print("Area of Square : ", area)



Area of Rectangle :  12
