h(t) is not periodic, so you cannot find it.

Explanation:

Since the period of sin(x) is 2π, the period of 4sin(3t) is 2π3, and the period of 3sin(3t) is 2π3. The period of the sum of those two periodic function would be the least common multiple of the two periods; however, there is no such common multiple. Hence, h(t) is not periodic.
