    To solve the problem shown above, you must apply the proccedure shown below:

    1. You have a l ine with a length of 9 centimeters.

    2. The line is enlarged by scale factor 7.

    3. Therefore, to find the new length of the line after the enlargement (Lt), you only have to multiply the initial length (L1=9 centimeters) by the scale factor (sc=7). Keeping this on mind, you have:

    Lt=L1xsc

    Lt = (9 centimeters) (7)

    Lt=63 centimeters

    4. What is the length of the line after the enlargement?

    The answer is: 63 centimeters.
