To find the area of a triangle on a coordinate grid, you can use the formula:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
In Luella's method, she multiplies \( \frac{1}{2} \) by \( 2 \), which could represent the \( \frac{1}{2} \) from the area formula, and \( 2 \) could represent the base of the triangle, assuming the height is involved in the next multiplication.
To complete the calculation, Luella needs to multiply the result of \( \frac{1}{2} \times 2 = 1 \) by the height of the triangle.
Looking at the answer choices provided:
- For option A, \( 8 \) and \( 2 \), we can check if \( 1 \times \text{height} \) could equal \( \text{area} \):
- For option B, \( 6 \) and \( 4 \):
- For option C, \( 8 \) and \( 10 \):
Assuming heights \( 4, 2, \) and \( 10 \) in relation to the provided areas, the height that helps to calculate an area consistent with common geometric principles could be determined.
To find a proper context for Luella's steps, we can consider triangle values quickly.
If we interpreted \( 2 \) as the base, the complementary height might be \( 4 \), since \( \frac{1}{2} \times 2 \times 4 = 4 \).
Thus the answer \( \boxed{4} \) aligns with the option structure hinting that option B could underline correct numbers yielding a result consistent with triangle area investigations:
The complete option considered is:
B: 6, 4 correspondingly assuming among available dimensions, yielding calculative area standards:
- Pick up 4 as height setting base-area calculations justified on foundational geometry.
