Will someone please tell me what I got correct and what I got incorrect

What you got right:

0.5 - Possible

48 - Possible

-6 - Not possible

0 - Not possible

BUT

3 is possible

Step-by-step explanation:

When we want to know the side lengths of a rectangle and we have possible choices, we want to look at if it's in the realm of possibility. That is, if it's physically possible. You have 5/6 correct, so I think you've done a good job so far. But what you got wrong was the statement that 3 is not possible.

3 is possible, because 24 is divisible by 3. The length would then be 8. So, what you should have put is that 3 is Possible.

(my comment on someone else's answer is incorrect, you only got one wrong, my bad)

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
