C^2=a^2+b^2
6^2=5^2+b^2
36=25+b^2
b^2=36-25
b^2=11
b= √11
b=3.3166
If you need to round it to the tenth place,
b~3.3
to hundreds place,
b~3.32
Good luck

<h3>What is sentence correction?</h3>
Sentence correction or sentence improvement is a type of grammatical practice where a sentence is given with a word or a phrase that requires grammatical changes or improvement.
Now,
- Here, we are talking about each of the mentioned structures.
- By grammar, everything used for them must be singular.
- But as mentioned in the sentence in part D, the plurals "they were" are used, which is the faulty part of the sentence.
Hence, Option D is the correct part that needs correction; the correction would be: "it was built."
