An Excel VBA function with two arguments

This article is part of my series: Excel VBA & Macros – A Step by Step Complete Guide.

In this example, I am going to write a VBA function that will calculate the area of a rectangle. We know the area of a rectangle= Length ☓ Width.

A rectangle.

This is a very simple function. Below shows the code:

Function Area(Length, Width)
    'Finding out the Area of the Rectangle.
    Area = Length * Width
    MsgBox "The Area of your Rectangle is: " & Area
End Function

This function takes two arguments(Length and Width) from the user and shows the area of the rectangle in a message box.
