Plz help! Plz EXPLAIN! :( Is this an example of Fair Use? Why or WHY OR WHY NOT?

Darren uses Photoshop to create a new version of the Mona Lisa by Leonardo da Vinci (view slide presentation in class). He uses this image on his website where he sells other photos he's created.

The answer will be that you would have to have a perment to use artworks and copy them also to your answer. This would not be an example of fair use.

Explanation:Fair use is a legal doctrine that promotes freedom of expression by permitting the unlicensed use of copyright-protected works in certain circumstances. ... Nature of the copyrighted work: This factor analyzes the degree to which the work that was used relates to copyright's purpose of encouraging creative expression.

perimeter = 2l +2w, divide total perimeter by 2 for total length of 1 side and 1 width

172/2 = 86 (  total for 1 side and 1 width)

86-24 = 62 (since length is 24 ft longer subtract 24 then divide by 2 for width)

62/2 = 31

width = 31 feet

length = 31 +24 = 55 feet

check: 31*2 = 62, 55*2 = 110,  110+62 = 172

a chromatic scale uses the twelve tones of the octave, while a regular scale only uses eight, or seven different notes (as the first note is played twice)
