You don't have enough movement to move and strike.
You can long jump a distance based on your Strength, which in your case is 10, which is 5 short. But, for the sake of coolness, if you can get a DC 15 Acrobatics check I'll let you make the jump anyway. You'll land in the southern window, which will put you in striking range of the goblin with Akyra, and you can attack this turn.
If you fail, but get at least 10, I'll let you get to that same spot, but not be able to attack, or you can go to the round and run back in through the entrance, but your movement will only get you onto the squares with the broken doors.
