Question
Write a VB Program that calculates the area of a rectangle give that the area = lengthmultiplied by width.
Solution 1
Sure, here is a simple VB.NET program that calculates the area of a rectangle:
Module Module1
Sub Main()
Dim length As Double
Dim width As Double
Dim area As Double
Console.Write("Enter the length of the rectangle: ")
length = Convert.ToDouble(Console.ReadLine())
Console.Write("Enter the width of the rectangle: ")
width = Convert.ToDouble(Console.ReadLine())
area = length * width
Console.WriteLine("The area of the rectangle is: " & area)
Console.ReadKey()
End Sub
End Module
This program works as follows:
- It declares three variables:
length,width, andarea. - It prompts the user to enter the length of the rectangle and stores the input in the
lengthvariable. - It prompts the user to enter the width of the rectangle and stores the input in the
widthvariable. - It calculates the area by multiplying the length by the width and stores the result in the
areavariable. - It outputs the area of the rectangle to the console.
Solution 2
Sure, here is a simple VB.NET program that calculates the area of a rectangle:
Module Module1
Sub Main()
' Declare variables
Dim length As Double
Dim width As Double
Dim area As Double
' Ask for user input
Console.Write("Enter the length of the rectangle: ")
length = Convert.ToDouble(Console.ReadLine())
Console.Write("Enter the width of the rectangle: ")
width = Convert.ToDouble(Console.ReadLine())
' Calculate area
area = length * width
' Display result
Console.WriteLine("The area of the rectangle is: " & area)
' Wait for user to close console
Console.ReadLine()
End Sub
End Module
This program first declares three variables: length, width, and area. It then asks the user to input the length and width of the rectangle, and stores these values in the respective variables. The area is then calculated by multiplying the length and width together. Finally, the program outputs the calculated area to the console.
