You needed to explain it in terms of the two variables, so not stating area would likely cost you a mark

It didn't ask to round to the nearest kilogram. Besides, if you rounded to 16kg, it would have been a loss, whereas 15kg would still be a profit as 15.2kg was the break-even point.

If the question required it to one decimal place and you gave a rounded answer, then yes you would lose a mark.
