In the given figure, the triangle \( \triangle PQR \) is divided into three smaller regions by lines from \( P \) to the base \( QR \). The areas of these smaller regions are provided: 5, 10, and 8 square units.

Let’s break down the problem:

1. The area of \( \triangle PQR \) is the sum of the areas of these smaller triangles. Hence, we can calculate the total area of \( \triangle PQR \) as:
\[
\text{Area of } \triangle PQR = 5 + 10 + 8 = 23 \, \text{square units}.
\]

It seems that there might be additional information or a misunderstanding of the specific regions intended by the question. Since the total of the given areas does not match any of the provided options (41, 45, etc.), could you clarify if any specific regions are meant to be calculated?

Feel free to ask for more detailed clarification or upload any additional images for further guidance.

Let me know if you'd like more detailed steps or another approach! Here are five related questions:
1. How can we determine the area of a triangle using the base and height?
2. What is the significance of dividing a triangle into smaller areas?
3. How can we apply Heron's formula to find the area of a triangle given the sides?
4. What are some common methods for calculating areas of irregular shapes?
5. How does the area of sub-triangles relate to the area of a larger triangle?

**Tip**: For geometry problems like these, visualizing or sketching the regions carefully often helps to identify relationships between areas more easily.

In the adjoining figure, all numerals represent the area of that region in square units. Find the area of triangle PQR in square units.
