If you would like to dilate a square with a side length of 8 units to create a square with a side length of 20 units. What scale factor should you use? Write your answer in decimal form
To find the scale factor needed to dilate the square with a side length of 8 units to a square with a side length of 20 units, we can use the formula:
Scale factor = new side length / original side length
Scale factor = 20 / 8
Scale factor = 2.5
Therefore, the scale factor needed to dilate the square is 2.5.
