A rectangular poster has a length of 70 centimeters and a width of 20 centimeters. The poster is reduced in size by 5 centimeters in length and 2 centimeters in width. What is the area of the new poster?
*
1170 square centimeters
1080 square centimeters
1400 square centimeters
10 square centimeters
The area of the original poster is 70 cm * 20 cm = 1400 square centimeters.
After reducing the length by 5 cm and the width by 2 cm, the new dimensions are 65 cm in length and 18 cm in width.
Therefore, the area of the new poster is 65 cm * 18 cm = 1170 square centimeters.
So, the correct answer is:
1170 square centimeters
