37. Which aspect of an object should be measured with a ruler?
Answer: A
The length of a table should be measured with a ruler.
Measuring the length of a table is an appropriate use of a ruler, as rulers are specifically designed to measure linear dimensions.
A) The length of a table
This option is correct because a ruler is a tool that is used primarily for measuring length. It provides a straight edge with marked increments, making it suitable for determining the linear measurement of objects like tables.
B) The weight of a bag of oranges
This option is incorrect as weight is measured using scales, not rulers. A ruler cannot provide a measurement of weight; it is only capable of measuring dimensions such as length, width, or height.
C) The angle between two lines
This option is also incorrect since measuring angles requires a protractor, not a ruler. A ruler cannot accurately determine the degree of angle between two lines, which is a different type of measurement.
D) The volume of a glass of tea
This option is incorrect because volume is typically measured using liquid measuring cups or graduated cylinders. A ruler does not provide a means to measure the space that liquid occupies.
Conclusion
The correct answer is clearly A) The length of a table, as it aligns directly with the primary function of a ruler, which is to measure linear distances. All other options involve measurements that are outside the capabilities of a ruler, thereby rendering them incorrect.
