Simple Harmonic Motion equation rearrangement?

    1. The problem statement, all variables and given/known data
    Hello! I have a physics homework question I just need help at!
    What I am supposed to do is calculate the value for free-fall acceleration, ag, for each of my trials that I did in my lab. I supposed to use the equation for the period of the simple pendulum, T=2π√l/g, but I have to rearrange it to solve for ag. How would I do that?

    2. Relevant equations
    Here are some sample values I used in my lab:
    Length: 1 meter
    Period: 20.1 seconds

    3. The attempt at a solution
