Multiply the area of the rectangle by the square of the scale factor to get the area of reduced rectangle.
Reduced area = 720 * (1/6)^2
Reduced area = 720 * (1/36)
Reduced area = 720/6
Reduced area = ? sq in.
720/36=20 sq. in.
Let's say the original painting was 24x30"
24/6=4
30/6=5
4*5=20 sq. in., so the answer checks out!!
