The scale factor is the square root of the ratio of the areas.
Let's say the original triangle has area A, and the dilated triangle has area B.
According to the problem, B = 6.25A.
The scale factor is then √(B/A) = √(6.25A/A) = √6.25 = 2.5.
Therefore, the scale factor is 2.5.
A triangle on a coordinate plane was dilated. After being dilated, its area is 6.25 times as great as the original figure. What was the scale
factor?(1 point)
