Answer: 72 inches!
Step-by-step explanation:
The length of the rectangular yard in inches is 72 inches. This is calculated by using the perimeter formula, p = 2l + 2w, and substituting the known values: p = 2(18 feet) + 2(4 feet). This simplifies to p = 36 feet + 8 feet, which is equal to 44 feet. To convert this to inches, we multiply 44 feet by 12 inches per foot, which gives us a total of 528 inches. Therefore, the length of the rectangular yard in inches is 72 inches.
