Answer:
The program written in Python is as follows:
<em>See Explanation section for line by line explanation</em>
for n in range(100,1000):
isum = 0
for d in range(1,n):
if n%d == 0:
isum += d
if isum == n * 2:
print(n)
Explanation:
The program only considers 3 digit numbers. hence the range of n is from 100 to 999
for n in range(100,1000):
This line initializes sum to 0
isum = 0
This line is an iteration that stands as the divisor
for d in range(1,n):
This line checks if a number, d can evenly divide n
if n%d == 0:
If yes, the sum is updated
isum += d
This line checks if the current number n is a double-perfect number
if isum == n * 2:
If yes, n is printed
print(n)
<em>When the program is run, the displayed output is 120 and 672</em>

Answer:
D. Change the def to def area (width, height = 12)
Explanation:
Required
Update the function to set height to 12 when height is not passed
To do this, we simply update the def function to:
def area (width, height = 12)
So:
In boxlarea = area (5,2), the area will be calculated as:

In box2area = area (6), where height is not passed, the area will be calculated as:
