To find the length of the fourth side, we subtract the sum of the lengths of the three known sides from the perimeter.
Perimeter of the trapezoid = 24 yd
Sum of the lengths of the three known sides = 3 yd + 6 yd + 9 yd = 18 yd
Length of the fourth side = Perimeter - Sum of the lengths of the three known sides = 24 yd - 18 yd = <<24-18=6>>6 yd. Answer: \boxed{6}.
