you don't need actual value you can also do 1/2 x precision
so 0.1 (precision) x 1/2 =0.05
so 0.1 (precision) x 1/2 =0.05

sorry I have 2 questions:
1. where did you get 0.1 from?
2. when I do 0.1 x 10 x 1/2 you get 0.5, not 0.05
1. I think the 0.1 comes from "correct to one decimal place".
2. The formula is
Looked at another way, if the length is 10.0 m, that means it could be anything that would round to 10.0 m.
So, it could be 9.95 m. Or 9.962704168324689 m. Or 10.0264 m. Or anything satisfying
The absolute error is the biggest possible difference between the actual value and 10.0, which is
The precision mentioned above is the range from 9.95 to 10.05, which is 10.05 - 9.95 = 0.1, and half of it is 0.05.
By either method, the answer is D.

0.1 is the precision which is the smallest unit you can get from 10.0
so according to the formula
0.1 x1/2 =0.05
Hope that makes sense
