What is the length of an aluminum rod at 65 degress celcius if its length at 15 degrees celcius is 1.2 meters?

Finallength-initiallength=coefficentlinearexpansion*(65-15).

You can get the coefficent of linear expansion for aluminum from your text or a handbook.

I don't understand, can someone else help me? Thank You.
