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 value should the
student report as the area? Explain your answer.

Sagot :

Dimensions of a table and recorded the length as 103.50 cm and the width

as 73.75 cm

AREA = L × B

AREA = 103.50 × 73.75

area = 7,633.125 cm²

but the student should report 7633 cm² because the width measurement (73.75 cm) has 4 significant figures while the length measurement (103.50 cm) has 5 significant figures and when multiplying the answer should have the same number of significant figures as the number with the least number of sig figs.

  • Significant Figures can help determine the accuracy of a number by the number of significant figures it contains.

so the correct answer should be 7633 cm².
