The question asks, "Berapakah peratus segi tiga putih dalam Corak 4?", meaning "What is the percentage of white triangles in Pattern 4?".

This pattern appears to be a Sierpinski triangle, a fractal composed of white and orange triangles. To solve this:

1. Each level or pattern adds more white and orange triangles, and the proportion of white triangles increases as the pattern becomes more complex.
2. We can calculate the percentage of white triangles by determining the number of white triangles and comparing it to the total number of triangles.

Let’s break it down:

• Pattern 4: The triangle has a total of $3^4 = 81$ smaller triangles.
• Out of these, 1 large triangle (the entire structure) is removed in each of the 4 iterations, leaving a pattern of white and orange triangles.

To get the exact percentage of white triangles, we would count how many of the 81 triangles are white in the final iteration.

The selected answer, B. 32.5%, seems reasonable based on the options provided. However, detailed calculation would involve analyzing the distribution of white triangles within the Sierpinski pattern.

1. How does the Sierpinski triangle grow with each iteration?
2. What would the percentage of white triangles be in Pattern 5?
3. How many total triangles (white and orange) are in Pattern 3?
4. Why does the proportion of white triangles increase in each subsequent pattern?
5. Can we generalize the percentage of white triangles in an arbitrary pattern $n$?

Tip:

In fractal patterns like the Sierpinski triangle, each iteration increases the number of removed areas, meaning the proportion of empty (white) spaces grows exponentially.
