Task Solution: Finding the Difference in Area between Notebook and Book Pages

To solve this problem, we need to find the area of the book page and the area of the notebook page, and then calculate the difference between the two.

Given: - The area of the book page is 216 square cm. - The area of the notebook page is 1/3 of the book page.

Calculations:

1. Area of the Book Page: - Given: Area of the book page = 216 square cm.

2. Area of the Notebook Page: - Given: The area of the notebook page is 1/3 of the book page. - Calculation: Area of the notebook page = (1/3) * 216 = 72 square cm.

3. Difference in Area: - Calculation: Difference = Area of the book page - Area of the notebook page - Difference = 216 - 72 = 144 square cm.

Therefore, the area of the notebook page is 144 square cm less than the area of the book page.

Final Answer:

The area of the notebook page is 144 square cm less than the area of the book page.
