The time is
Explanation:
Resolving in the vertical direction
The initial velocity is
The time to reach the greatest height is
Applying the equation of motion
The time is
The time taken to land is twice the time to reach the greatest height

Explanation:
Here you actually asked about the wandering period of the projectile.
The initial velocity,
The throwing angle of the projectile,θ=
The wandering period of the projectile,
we know that,
