**Jai**, Tuesday, March 29, 2011 at 10:18amthe opposite angle of the shorter leg is the smaller angle (which is the 30 degrees)

since in a 30-60-90 triangle, the hypotenuse is twice the shortest side, and the longer leg is sqrt(3) times the shortest side:

hypotenuse: 2*5.4 = 10.8 ft

longer side: sqrt(3)*5.4 = 9.353 ft

perimeter is just the sum of all lengths of the sides:

5.4 + 10.8 + 9.353 = 25.553 ft

hope this helps~ :)

**Evi**, Saturday, March 23, 2013 at 11:57pmThe shorter leg + The shorter leg times 2 + The shorter leg times the square roots of 3.

2.4 + 4.8 + (2.4 times the square roots of 3)

2.4 + 4.8 + 4.16 = 11.36
