Which item is used as a measuring instrument for long distances?

• A. Measuring wheel
• B. Ruler
• C. Caliper
• D. Tape measurer, rule tape

Answer: (D)

Measuring long distances relies on a flexible, extendable instrument that can be laid along a line and read directly at the end. A tape measure fits this role best: you pull the tape taut, and the markings along its length give the distance in the chosen units, making it practical for long spans and easy to use on-site. Ruler and caliper are meant for short, precise measurements of small objects, so they don’t suit long-distance tasks. A measuring wheel can cover long distances, but it often introduces error from wheel size, surface irregularities, or slippage, whereas a tape measure provides a direct, readable measurement for lengthy straight lines.
