Dimensional analysis for Pendulum

The period of a simple pendulum, defined as the time necessary for one complete oscillation, is measured in time units and is given by
T=2pi sqrt(l/g)
Where l is the length of the pendulum and g is the acceleration due to gravity, in units of length divided by time squared. Show that this equation is dimensionaly consistent. (You might want to check the formula using your keys at the end of a string and a stopwatch.)

1) What are the dimensions of g?

2) What is the dimension of sqrt(l)?
