1 Introduction ANSWERS TO MULTIPLE CHOICE QUESTIONS 1. Using a calculator to multiply the length by the width gives a raw answer of 6783 m 2 ‚ but this answer must be rounded to contain the same number of significant figures as the least accurate factor in the product. The least accurate factor is the length‚ which contains either 2 or 3 significant figures‚ depending on whether the trailing zero is significant or is being used only to locate the decimal point. Assuming the length contains 3 significant
