Consider two triangles, Triangle A and Triangle B, both of which are right triangles. Triangle A has legs of length 6 and 8 units. Triangle B has legs of length 9 units and 12 units.
Determine the relationship between the areas of the two triangles. The area of a triangle can be calculated using the formula:
$A = \frac{1}{2} \times \text{base} \times \text{height}$
What is the comparison between the area of Triangle A and the area of Triangle B?
