The original area of the poster is:
Area = length * width
Area = 72 cm * 15 cm
Area = 1080 cm^2
After reducing the size of the poster, the new length is 72 cm - 6 cm = 66 cm and the new width is 15 cm - 3 cm = 12 cm.
The area of the new poster is:
Area = new length * new width
Area = 66 cm * 12 cm
Area = 792 cm^2
Therefore, the area of the new poster is 792 cm^2.
