Question

2 solve apply the concepts to this problem. all nonzero digits are significant (rule 1). use rules 2 - 3 to determine the areas are significant. a. three (rule 1) b. five (rule 2) c. five (rule 4) d. unlimited (rule 6) e. four (rules 2, 3, 4) f. two (rule 5) problem - solving 3.2 solve problems with the help of an interactive chemasap. figures in calculations a calculator to find the area of a floor that measur 4 meters. the calculator would give an answer each of the measurements expressed to four significant two significant figures used in the calculation

Explanation:

Step1: Identify significant - figure rules

The problem mentions using significant - figure rules for calculations. For non - zero digits, they are always significant.

Step2: Analyze the given lengths

Since the lengths are given to four significant figures, the result of the area calculation (area = length×width) should also be reported to four significant figures according to the rules of significant figures in multiplication.

Answer:

The area should be reported to four significant figures.
