According to my calculations the theoretical answer about to be given is number c
Point three-hundred and nine
zero point three-hundred and nine
The square root of 5/2 is 2.236067978. The square root of 18 is 4.242640687. The total of 2.236067978 plus 4.242640687= 6.478708667.
If you rounded up to two decimal points. You will get 6.48. It depends what digit your question is telling you to round up to.
Hope it helps.
