Is the noun phrase 'side lengths to the nearest tenth' grammatically correct?

Question

Here is a sentence extracted from the entire question sentences, one from this exercise page on Khan Academy.

The following figure shows △ABC with side lengths to the nearest tenth.

I thought the above sentence was missing the word 'rounded', so that should have been:

The following figure shows △ABC with side lengths rounded to the nearest tenth.

Is the sentence from Khan Academy natural and grammatically correct, or my guess is right?

Answer 1

Their version is completely understandable and unambiguous to me.
Some word has been elided...

shown/listed/rounded to the nearest tenth

bu there's no difficulty in supplying it. The units after "tenth" are also omitted.

Your version is fine too.
