Area of Rectangle
To find the area of a rectangle whose length and breadth are given, use the following formula.
Area of Rectangle = length * breadth
Program
In the following program, we shall define a function areaOfRectangle() that takes length and breadth as arguments and return the area of rectangle.
We read length and breadth as integers from user, call areaOfRectangle() with the length and breadth passed as arguments. You can also read length and breadth as floating-point numbers from user using float() function. In the following program we use int() and you may try float() as practice.
Input
length, breadth of rectangle, where length > 0 and breadth > 0.
Python Program
def areaOfRectangle(length, breadth) :
if length < 0 or breadth < 0:
print('Length or breadth cannot be negative.')
return
return length * breadth
length = int(input('Enter length : '))
breadth = int(input('Enter breadth : '))
area = areaOfRectangle(length, breadth)
print(f'Area of Rectangle : {area}')
CopyOutput
Enter length : 5
Enter breadth : 8
Area of Rectangle : 40
Important Points regarding above program
- input() function reads a string from standard input. Therefore, we have used int() function to convert string to integer.
- If given length or breadth is less than zero, we are returning nothing.
