Okay i need with this question. sophie is planting a garden. her garden is divided into equal sections, each measuring 4 meters in length. which could be the total length of her garden?

When you say "Which ... ", I know there's supposed to be a list of choices,
and you're supposed to pick out the one from the list that could be correct.
I have no way to help you make that selection if you won't share the list.

Find a multiple of  4  on the list, and that's the one you want.
