Final answer:
The correct standard form for one hundred and four thousandths of a meter is 0.104 meters, which is answer choice (b).
Step-by-step explanation:
The correct answer to the question is that the side of the football field Nick measured is 0.104 meters long. When we express 'one hundred and four thousandths of a meter' in numerical form, we write it as 0.104. This is because the term 'thousandths' points to the third decimal place, which is the same as dividing the integer 104 by 1000, resulting in 0.104. Therefore, the correct length in standard form is 0.104 meters (b).
