Final answer:
For small items, use a ruler, and for slightly larger things, a yardstick is good. For longer distances, a measuring tape with both customary and metric units is the best choice for flexibility and length.
Step-by-step explanation:
When selecting a measurement tool for length-based measurement, the key is to consider the size of the object or distance being measured. For small items, a ruler is appropriate. It is typically 12 inches in length and provides measurements in both inches and centimeters. For slightly larger distances, a yardstick can be a good choice, as it measures 3 feet or 1 yard in length.
However, for even longer distances, a measuring tape is often the best option. A measuring tape is flexible and can measure longer lengths than a ruler or yardstick. It usually includes both customary and metric units, which is helpful for diverse measurements. For measurement of the length of objects like a large picture frame or the distance across a room, a tape measure would be suitable, providing the flexibility and length required for such tasks.
