Answer:

If you're scaling up from a smaller figure to a larger one, plug the lengths into the equation scale factor = larger length over smaller length. If you're scaling down from a larger figure to a smaller one, use the equation scale factor = smaller length over larger length.

Dilatation help us solve real world problems by allowing us to estimate the location that something has to be in or even if an object will fit or not.
