The measure of one of the smaller base angles of an isosceles trapezoid is 60 degrees. The shorter base is 5 inches long and the altitude is 3 sqrt 3 inches long. What is the number of inches in the perimeter of the trapezoid?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The length of the longer base is 2(3√3 / √3) + 5 = 11
The length of the leg(s) is sqrt[(3√3)2 + 33] = 6
The perimeter is P = 5 + 11 + 2*6 = 28 inches ☺
