A Rectangle is a planar shape which have its opposite sides being equal like a closed shape having sides as 4, 4, 5, 5 with opposite sides being equal will be a Rectangle. Mathematically area of Rectangle can be found by just multiplying it’s sides. For example – **If a rectangle have sides a, a, b, b then area of it will be a * b**. Quite simple just multiplication.

Let’s Program this as **Python Code for Finding Area of Rectangle**.

```
# Finding Area of a Rectangle using Python
# Ask User for two sides of Rectangle
a = float(input("First Side of Rectangle => "))
b = float(input("Second Side of Rectangle => "))
# Multiply together two sides inputted by user
area_of_rectangle = a * b
# Printing out area of rectangle
print("Area of rectangle is =>", area_of_rectangle)
```

**Output of Above Code**

```
First Side of Rectangle => 4
Second Side of Rectangle => 5
Area of rectangle is => 20.0
```
