Since the first side is given in feet and the last two sides are given in inches, we need to convert the first side to inches. We know that 1 foot is equal to 12 inches, so 0.75 feet is equal to 12 * 0.75 = <<12*0.75=9>>9 inches.
Therefore, the lengths of the four sides of the rectangle are 9 inches, 9 inches, 5 inches, and 9 inches.
The length of the fourth side is 9 inches. Answer: \boxed{9}.
