Answer:
The scale factor from triangle A's area to triangle B's area is [tex]\frac{1}{9}[/tex]
Step-by-step explanation:
Given that triangles A and B are scaled copies of each other.
Area of triangle A = [tex]8 unit^2[/tex]
Area of triangle B = [tex]72 unit^2[/tex]
The scale factor from triangle A's area to triangle B's area:
[tex]\frac{\text{Area of A}}{\text{Area of B}}=\frac{8 unit^2}{72 unit^2}=\frac{1}{9}[/tex]
The scale factor from triangle A's area to triangle B's area is [tex]\frac{1}{9}[/tex]
