A Rectangle is a planar shape which have its opposite sides being equal like a closed shape having sides as 3, 3, 6, 6 with opposite sides being equal will be a Rectangle. Mathematically **Perimeter of Rectangle** can be calculated by just adding all of four sides. For example – If rectangle have sides 7, 7, 4, 4 then perimeter will be 7 + 7 + 4 + 4 = 22, in order words if rectangle have sides defined as x, x, y, y where **x is length** and **y is height** => then **perimater will be 2 * (x + y)**. Quite simple mathematical formula for calculating perimeter of rectangle.

Let’s program this as Python Code for **Finding Perimeter of Rectangle**.

```
# Calculating Perimeter of Rectangle Using Python
x = float(input("Enter Length of Rectangle => "))
y = float(input("Enter Height of Rectangle => "))
# Perimeter of Rectangle
perimeter_of_rectangle = 2 * (x + y)
# Printing out parameter of Rectangle
print("Perimeter of Rectangle is =>", perimeter_of_rectangle)
```

**Output of Above Code**

```
Enter Length of Rectangle => 3
Enter Height of Rectangle => 4
Perimeter of Rectangle is => 14.0
```
