How can i solve this Fourier Transform question???

1. The problem statement, all variables and given/known data

f(t)= a/((a^2)+(t^2)) if a>0 find the fourier transform

2. Relevant equations

Just give me a hint to solve or first step for solving. Then i will solve.

3. The attempt at a solution

Thanks for help.
