A triangle on a coordinate plane was dilated after being dilated. The area is 6.25 times greater than the original figure what was the scale factor
If the area of a triangle after dilation is 6.25 times greater than the original figure, then the scale factor of the dilation can be found by taking the square root of 6.25, since area is proportional to the square of the scale factor.
Therefore, the scale factor is √6.25 = 2.5.
