Go language program to calculate trapezoid area

Following program shows you how to calculate trapezoid area. This program gets trapezoid base and height from user and calculates area and prints it using following formula Area = (base1 + base2) X height /2

package main

import "fmt"

func main() {

  var trapezoidBase1 float64
  var trapezoidBase2 float64
  var trapezoidHeight float64
  var areaOfTrapezoid float64
  fmt.Println("Please enter base1 of trapezoid:")
  fmt.Scanf("%f", &trapezoidBase1)
  fmt.Println("Please enter base2 of trapezoid:")
  fmt.Scanf("%f", &trapezoidBase2)
  fmt.Println("Please enter height of trapezoid:")
  fmt.Scanf("%f", &trapezoidHeight)
  areaOfTrapezoid = (trapezoidBase1 + trapezoidBase2) * trapezoidHeight / 2
  fmt.Println("Area of trapezoid is: " ,areaOfTrapezoid)
}

Output:

Please enter base1 of trapezoid:
 12
Please enter base2 of trapezoid:
 16
Please enter height of trapezoid:
 18
Area of trapezoid is:  252
