1.2 m = 120 cm
Let the shorter piece be x, then the longer piece is 2x + 15. So we have:
x + 2x + 15 = 120
3x + 15 = 120 subtract 15 to both sides
3x = 105 divide by 3 to both sides
x = 35
Thus the shorter piece is 35 cm.

Can you slide on the pintail 37 by original?
Yes, you can slide any board. The fact that it is a pintail does not make it any easier or harder to slide. However, the length of your board will affect how it slides. Because you have a shorter than average sized longboard, (average being about 42") the board will break free from the road and go into a slide fairly easily. However you will not have as much control in your slide as you would if you had a longer board. Shorter boards break free more easily than longer boards, but are more difficult to control in a slide. Longer Boards do not break free as easily, but once they do they make for a more predictable and controllable slide.

The strings on the harp vibrate, that vibration resonates in the sound board. The thichnes and the length of the string, as well as the material and construction of the string determine frequency.
