Answer:
A. 72
Step-by-step explanation:
Determinant of a 2x2 matrix: ad - bc
In that case,
24(18) - 30(12)
432 - 360
72
And we have our answer.
Coordinates of vertices of new triangle:
A´(0,0), B´(-12,0), C´(-6,12).
This transformation is dilatation, with the origin as the center of dilatation and the scale factor of the dilatation : s=3. A dilatation changes the size of a figure, while the shape of figure does not change.
Triangle A´B´C´ (image) is similar to triangle ABC (pre-image) because their corresponding angles are equal in measure and the ratio of their corresponding sides are in proportion (in attachment).
