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.

Answer 1

The scale factor can be calculated by dividing the length of the new square by the length of the original square.

Scale factor = length of new square / length of original square

In this case, the length of the new square is 20 units and the length of the original square is 8 units.

So, scale factor = 20 / 8 = 2.5

Therefore, the scale factor to dilate a square with a side length of 8 units to create a square with a side length of 20 units is 2.5 (in decimal form).
