# Area of Rectangle in C#

## Area of Rectangle Program in C# with Examples

In this article, I am going to discuss how to calculate the Area of a Rectangle in C# with Examples. So, here, first, we will discuss what is Rectangle, then we will discuss how to calculate the area of a rectangle and finally, we will see how to implement this program in C#.

##### What is a Rectangle?

A rectangle is a 2-Dimensional shape in geometry, having 4 sides and 4 corners. Its two sides meet at right angles. Thus, a rectangle has 4 angles, each interior angle is 90 ÌŠ. The opposite sides of a rectangle have the same lengths and are parallel.

##### How to Calculate the Area of a Rectangle in C#?

Area of rectangle = length * breadth Or
A=L * B
Where A is the area of the rectangle
L is the length of the rectangle
B is the breadth of the rectangle

For Example: Let say: L i.e. Length =20 and B i.e. Breadth=5
Then the area of the Rectangle is 100
Explanation: Area of rectangle is the multiply of length (L) and breadth (B)
L=20, B = 5 So, L * B = 20 * 5 = 100

##### Logic to Calculate the Area of Rectangle in C#Â Â Â

For finding the area of the rectangle we simply need to multiply length and breadth. The following are the steps to follow to solve this problem.Â Â Â

1. First, we will define length L and breadth B.Â Â Â
2. Then we will define the area of rectangle A.Â Â Â
3. Then calculate the area of the rectangle by multiplying the length(L) and breadth(B).Â Â
4. After multiplying result will assign in A and showÂ the output.Â Â
##### Example: Area of Rectangle Program in C#.

The following C# Program will calculate the area of the rectangle.

```using System;
public class AreaOfRectangle
{
public static void Main()
{
int Length = 15;
int Area = Length * Breadth;
}
}
```

OUTPUT: Area of Length 15 and Breadth 6 Rectangle is 90Â

##### Example: Area of Rectangle Program in C# by taking input from the user

The following C# Program will allow the user to input the length and breadth of the rectangle and then calculate the area and display it on the console.

```using System;
public class AreaOfRectangle
{
public static void Main()
{
Console.WriteLine("Enter the Length of a Rectangle: ");

Console.WriteLine("Enter the Breadth of a Rectangle: ");
