Final answer:
The question involves working with significant figures and unit conversion in measuring the dimensions of a rectangle, multiplying and adding measurements, and rounding to the correct number of significant figures.
Step-by-step explanation:
The question pertains to the calculation of a measurement and unit conversion, which involves significant figures and rounding. When the dimensions of a rectangle are measured and reported, it is essential to use the correct number of significant figures to reflect the accuracy of those measurements. For example, if a rectangle's width is measured as 1.25 cm, this should be recorded with three significant figures. Additionally, the problem includes unit conversion examples such as converting meters to centimeters, where by formal procedure, 3.55 m equals 355 cm. Furthermore, calculations such as multiplying measurements or adding quantities require attention to significant figures in the final answer, where the number of significant figures in the result is determined by the measurement with the fewest significant figures.
To perform calculations with significant figures, one must follow certain rules, such as keeping track of significant figures during multiplication, division, addition, and subtraction. An example given is 0.048 m x 32.97 m, which required rounding to two significant figures. Moreover, when performing subtraction, consideration must be given to the least precise measurement, like subtracting 362 m from 78,500 m and rounding the result to the nearest hundredth.
