Final answer:
To calculate the area of the folder not covered by the sticker, multiply the folder's dimensions to find its total area, calculate the sticker's area, and then subtract the sticker's area from the total area. The result is 86 square inches that are not covered by the sticker.
Step-by-step explanation:
To find the number of square inches of the folder that is not covered by the sticker, we need to calculate the total area of the folder and subtract the area covered by the sticker.
The area of the folder is the product of its length and width: 11 inches × 8 inches = 88 square inches.
The area of the sticker is similarly the product of its length and width: 2 inches × 1 inch = 2 square inches.
To find the area not covered by the sticker, we subtract the area of the sticker from the area of the folder: 88 square inches - 2 square inches = 86 square inches.
Therefore, 86 square inches of the folder are not covered by the sticker.
