...correct number of digits.)? A fisherman catches two striped bass. The smaller of the two has a measured length of 91.47 cm (two decimal places, four significant figures), and the larger fish has a measured length of 120.2 cm (one decimal place, four significant figures).
 
91.47+120.2=211.67.

Number of significant figures is irrelevant in this cause since your answer isn't derived from say a multiplication.
The extra significant figures does not imply any more accuracy in the measurement of say the second fish, rather the communal total is just that, the entire length of all the fish.
