Identify Scale Factor: Identify the scale factor for the enlargement by comparing the new width to the original width. $\newline$ Calculation: Scale Factor = $\frac{\text{Enlargement Width}}{\text{Original Width}} = \frac{22.5 \, \text{cm}}{7.5 \, \text{cm}} = 3$ .
Calculate Scale Factor: Apply the scale factor to the original length to find the length of the enlargement. $\newline$ Calculation: Enlargement Length = Original Length $*$ Scale Factor = $10.0$ cm $*$ $3$ = $30.0$ cm.
