How do you know what scale factor to use?

Answer 1

To determine the appropriate scale factor, you first need to identify the relationship between the original size and the desired size of the object or figure. This can be achieved by measuring the dimensions of both the original and target shapes, then dividing the target size by the original size. The resulting ratio gives you the scale factor, which can be used to resize your object accurately. Additionally, consider the context of the problem, as certain situations may dictate specific scale factors.
