Rod Oven

Can anyone actually explain to me how this mathematics question was does as I had it in an engineering test?

Can anyone actually explain to me how this mathematics question was does as I had it in an engineering test but couldn't do it:
You need to determain whether the length of copper a copper rod oven will expand by more than 2% of the original length when heated. Information you have suggests that heating to 1500 degrees C, will not result in greater expansion the the required 2%.
1)Is this information correct?
2) If not, what is the maximum temperature the rod can be heated to in order to stay within the expansion limits?
The information you have is:
The equation relating original length 'I*o' and length 'l' at temperature 't'.
l= l*o(1+at) 'a' is the coefficient of linear expansion, and 't' is the temperature.
Values given are 'I*o' = 0.250m, 'a'= 1.7× 10 to the power -5.

I would appreciate any help with this question as a question similar will come up on my JAR 66 aerospace engineering licence.

Thanks

1500* C is not acceptable as copper melts at 1084*C
