......[1]
where
T represents the Time period in second
l represents the length of the pendulum/
As per the statement:
Use the gravitational constant g = 9.8 m/s^2 , length of the simple pendulum(l) = 2 meters and 
Substitute the given values we have;

⇒
Therefore, the period, in seconds to two decimal places is, 2.84 sec
