Program for Area And Perimeter Of Rectangle
• Difficulty Level : Easy
• Last Updated : 24 Mar, 2021

A rectangle is a flat figure in a plane.It has four sides and four equal angles of 90 degree each.In rectangle all four sides are not of equal length like square, sides opposite to each other have equal length.Both diagonals of rectangle have equal length. Examples:

```Input : 4 5
Output : Area = 20
Perimeter = 18

Input : 2 3
Output : Area = 6
Perimeter = 10```

Formulae :

```Area of rectangle : a*b
Perimeter of ractangle: 2*(a + b)```

## C++

 `// CPP program to find area``// and perimeter of rectangle``#include``using` `namespace` `std;` `// Utility function``int` `areaRectangle(``int` `a, ``int` `b)``{``   ``int` `area = a * b;``   ``return` `area;``}` `int` `perimeterRectangle(``int` `a, ``int` `b)``{``   ``int` `perimeter = 2*(a + b);``   ``return` `perimeter;``}` `// Driver program``int` `main()``{``  ``int` `a = 5;``  ``int` `b = 6;``  ``cout << ``"Area = "` `<< areaRectangle(a, b) << endl;``  ``cout << ``"Perimeter = "` `<< perimeterRectangle(a, b);``  ``return` `0;``}`
