No, it is not. For it to be a perfect square, the square root of it would have to be an integer, but √120 ≈ 10.954. 100 and 121 are perfect squares nearest to 120. ■
One way is trial and error. The square root of 121 is 11. So the square root of 120 is just under that. 10.9 squared is 118.81 10.95 squared is 119.9. 10.954 squared is 119.99 which is close enough for me.

120 is not the square of an integer, its square roots, rounded to two decimal places, are ±10.95.
The answer, assuming that 120 is degrees and not radian is -square root of 3.
sqrt(120)
10.9545
120The answer is 120.
