Question: 3. A student measured the dimensions of a table and recorded the length as 103.50 cm and the width as 73.75 cm. According to the student's calculator, the area is 7633.125 cm2. What should the student report? Explain your answer.
The student should report the area of the table as 7633.13 cm². This is because in scientific measurements, the final result should be reported with the least number of decimal places used in the calculations. Here, the measurements of length and width are given to two and two decimal places respectively, hence the answer should also be rounded off to two decimal places.
