•Discussion: The length of the wood is twice the sum of the length
and the width of the painting. The cost of the wood is simply its length times its
cost per inch. For the canvas, we must add 5 inches to the length and width to allow
for wrapping the canvas around the frame.The area is length times width, converted
from square inches to square feet.
•Assumptions: The input values are positive (checking for erroneous data
is not done).
