# Arup Guha
# Program that calculates the area of a rectangle.
# 1/10/20

# We create two variables and set them to values via the assignment statement.
length = 20
width = 10

# Here we create a variable area and assign it to a value based on the
# values of other variables we currently have.
area = length*width

# Ta da!
print("The area of the rectangle is", area)

# Increment length by 1.
length = length + 1

# Now, look at the area.
print("The area of the rectangle is", area)

# Oops, we actually need to calculate this again.
area = length*width

# Now, look at the area.
print("The \"fixed\" area of the rectangle is", area)
