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, you need to divide the side length of the larger square by the side length of the smaller square.
In this case, the side length of the larger square is 20 units, and the side length of the smaller square is 8 units.
So, the scale factor can be calculated as:
Scale factor = Side length of the larger square / Side length of the smaller square
= 20 units / 8 units
= 2.5
Therefore, the scale factor you should use to dilate the 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.
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).
To find the scale factor needed to dilate a square, we can use the formula:
scale factor = new side length / original side length
In this case, the new side length is 20 units and the original side length is 8 units. Plugging these values into the formula:
scale factor = 20 / 8
Simplifying the fraction:
scale factor = 2.5
Therefore, the scale factor needed to dilate the square is 2.5.
