1-writing to explain- why might you need to measure a perimeter with a measuring tape instead of a ruler?
2-how are a ruler, a yardstick , and a measuring tape the same? how are they different?
i don't this answer please help
2- A ruler a yardstick and a measuring tape are the same because they can measuring items. A rule a yardstick and measuring tape different because they can't measuring the same length.
i don't know 1 answer please help me and i want to know number 2 is right or not
I do not know please help me

How are a ruler ,a yardstick and a measuring tape the same? How are they different.
1. To measure a perimeter, such as the perimeter of a room or an object, a measuring tape is often preferred over a ruler due to two main reasons:
a) Flexibility: A measuring tape is flexible and can be easily wrapped around curves and irregular shapes, providing a more accurate measurement of the perimeter. On the other hand, a ruler is typically straight and rigid, making it difficult to precisely measure lengths of curved or non-linear edges. For example, if you want to measure the perimeter of a circular table, a measuring tape can be positioned along the curve of the tabletop much more accurately than a ruler.
b) Length: Measuring tapes are usually longer than rulers, which makes them more suitable for measuring larger perimeters. Rulers typically measure in inches or centimeters and are usually between 12-18 inches long, whereas measuring tapes can easily extend up to several feet or meters, allowing for a single measurement of the entire perimeter without having to reposition the tool.
In summary, a measuring tape's flexibility and longer length make it a more practical tool for accurately measuring perimeters, especially for objects with curved or irregular shapes.
2. A ruler, a yardstick, and a measuring tape are all measuring tools, but they have some similarities and differences.
Similarities:
- All three tools are used for measuring lengths, distances, or dimensions.
- They can be made from various materials like metal, plastic, or wood.
- Units of measurement, such as inches, centimeters, or millimeters, are typically marked on all three tools.
Differences:
- Length: A ruler is usually the shortest, typically measuring up to 12-18 inches or 30-45 centimeters. A yardstick is longer, typically measuring around 36 inches or 91 centimeters. Measuring tapes, however, vary in length and can range from a few feet to several meters, depending on the model.
- Flexibility: A ruler and yardstick are rigid, whereas a measuring tape is flexible, enabling it to measure curved or irregular surfaces more accurately.
- Portability: A ruler is small and compact, making it easy to carry in a pencil case or pocket. A yardstick is longer and less portable, but still manageable. Measuring tapes can be compact like a retractable tape measure or longer like a contractor's tape measure, which may require more space to store and transport.
Overall, the differences lie in their length, flexibility, and portability, depending on the intended purpose and the type of measurements needed.
