Question

Imaginary triangles A and B are scaled copies of each other.Triangle B's area is 72 and triangle A's is 8 what is the scale factor from A to B? (Hint:it's not 9) than whats the answer

Answer 1

The scale factor from triangle A's area to triangle B's area is
`(1)/(9)`

Explanation:

Given that triangles A and B are scaled copies of each other.

Area of triangle A =
`8 unit^2`

Area of triangle B =
`72 unit^2`

The scale factor from triangle A's area to triangle B's area:

`\frac{\text{Area of A}}{\text{Area of B}}=(8 unit^2)/(72 unit^2)=(1)/(9)`

The scale factor from triangle A's area to triangle B's area is
`(1)/(9)`
