Ahmad bought a notebook for his younger sister as a birthday gift. Each page of the notebook is rectangular in shape. The breadth of the rectangle is 7 cm. The length is 12 cm longer. Find the area of the rectangle.

We are given the following information:

- Breadth of the rectangular page = 7 cm
- The length of the rectangular page = breadth + 12 cm

So, the length of the rectangle is:

\[
\text{Length} = 7 \, \text{cm} + 12 \, \text{cm} = 19 \, \text{cm}
\]

Now, we can calculate the area of the rectangular page using the formula for the area of a rectangle:

\[
\text{Area} = \text{Length} \times \text{Breadth}
\]

Substituting the values:

\[
\text{Area} = 19 \, \text{cm} \times 7 \, \text{cm} = 133 \, \text{cm}^2
\]

Therefore, the area of the rectangular page is **133 cm²**.

Do you have any questions or would you like further details?

Here are 5 related questions to explore:

1. How would the area change if the length were doubled?
2. What would the perimeter of the rectangle be with these dimensions?
3. How would you find the diagonal of this rectangle?
4. If the notebook had 100 pages, what would be the total surface area of all pages combined?
5. What is the relationship between length, breadth, and area for rectangles in general?

**Tip:** Always remember to double-check the units when solving area-related problems. The result should be in square units.
