In a two-story house with lap siding, the height intermediate landing is 61 1/2 inches. Which option lists this value as a possible measurement?

In a two-story house with lap siding, the height intermediate landing is 61 1/2 inches. Which option lists this value as a possible measurement?

• A. 55 inches
• B. 107 inches
• C. 61 1/2 inches
• D. 53 1/2 inches

Answer: (C)

The key idea is recognizing that an intermediate landing’s height is the vertical distance from the lower finished floor up to the surface of the landing, and this height can be expressed in fractional inches because of the various thicknesses of subfloor, flooring, and finishes. In this scenario, the given landing height is 61 1/2 inches, so the measurement that matches that value is the correct listing. The other numbers don’t match the specified landing height: they would imply a different vertical distance (either a much lower landing or roughly the height of a full story), which isn’t the measurement described.
