I dont really understand my homework and i need help!?

Question

For question number 8: The first length is 2.5 while the 2nd one is 5. So.... I know the answer of the third one is 5.6 but i don't really get question of 8a.

8a. Alex estimates that the unknown side length is about 4.5. How do you think Alex's estimate compares with the actual length. Explain your reasoning.

Answer 1

Explain your question. We don't have question 8 or 8a in front of us. I would be happy to help but don't have enough information.

Answer 2

If I read this correctly, the side is 5.6 but alex thinks it's 4.5.

Alex's estimate is 1.1 low.
