# Program to find Perimeter / Circumference of Square and Rectangle

• Last Updated : 06 Apr, 2021

The circumference of a figure is the sum of all the side lengths. To calculate the circumference of square, length of one of the side is required as all sides are equal. To calculate the circumference of rectangle, length and breadth of rectangle is required.

The circumference of a square is given by the formula:

```C = 4 * a
where a is the side length.```

Examples :

```input: 4
output: 16

input: 3
output: 12```

Circumference of a rectangle: The circumference of a rectangle is given by the formula:

```C = 2 * (l + W)
where l is the length and W is the width.```

Examples :

```input: 2 4
output: 12

input: 4 6
output: 20```
