This should be easy.

In a 30 60 90 triangle, short side = hypotenuse / 2 and the medium side = hypotenuse *sq root(3)/2 short side =9 and medium side = 0.8660254038 * 18 = 15.5884572681 So add all 3 for perimeter (info about 30 60 90 triangles here: http://www.1728.org/trig2.htm

Okay we know the sides are 18 + 9 + 18*sq root(3) /2 or 18 + 9 + 9*sq root(3)
