Magnifique--Bincent Ban Boe was a famous painter and mathematician. He was known for sketching self-portraits on small pieces of paper before completing the final painting on a large canvas.
Bincent made a note that 4 centimeters on his sketch corresponds to 60 inches on the actual portrait.
If the dimensions of the small sketch are 3 cm by 5 cm, how many square inches would he have to cover with paint in his final portrait?
"He would have to paint over..."

#2: Accurately computes actual measurements using the scale factor
#3: Accurately computes actual area using the correct area formula
