A regulation soccer field for international play is a rectangle with a length between 100 m and 110 m and a width between 64 m and 75 m.
When calculating the areas what is the appropriate number of significant figures?
multiplying/dividing: The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
adding/subtracting: final answer may have no more significant figures to the right of the decimal than the least number of significant figures in any number in the problem.
The Attempt at a Solution
The thing that is confusing me is what exactly "between 100 and 110" means with respect to uncertainty and sig-figs.
I know that 100 has 1 sig-fig and that 110 has 2 sig-figs and that 64 and 75 both have 2 sig-figs.
I understand that between 100 and 110 means value could be 100,101,102,103,104,105,106,107,108,109 or 110.
100 has1 sig-fig, 110 has 2 sig-figs, and 101,102,103,104,105,106,107,108, and 109 have 3 sig-figs.
Need some help thanks
