Physics: Post your doubts here!

Hi! O/N 2009 P22, Q.1 I am having difficulty deciding how many significant figures or decimal places to use... For L = 92±1 cm, the percentage uncertainty is 1.09%. Shouldn't we write the final answer as 1%, because the smallest no. of sig fig in the given data L = 92±1 is one? Thanks!
