A construction worker uses a steep tape to measure the length of an aluminum support column. If the measured length is 18.700 m when the temperature is 21.2 degrees celcius, what is the measured length when the temperature rises to 29.4 degrees celcius.

I found the increased lengths of the tape and the column, but I'm not sure how to relate them to find the reading on the tape measurer.
