The original area of the poster is calculated by multiplying the length by the width: 70 cm * 20 cm = 1400 square centimeters.

After reducing by 5 cm in length and 2 cm in width, the new dimensions are 65 cm in length and 18 cm in width.

The new area of the poster is then: 65 cm * 18 cm = 1170 square centimeters.

Therefore, the area of the new poster is 1170 square centimeters.
