The problem is that 5.5 feet is often mistakenly interpreted as 5 feet 5 inches. However, the decimal part represents a fraction of a foot, not inches. Since one foot equals 12 inches, 0.5 feet = 6 inches, so 5.5 feet is actually 5 feet 6 inches. To convert decimal feet correctly, multiply the fractional part by 12 to get the number of inches.
