correct but round to 215 feet

Why round to 215?

How do we round 214.45 to 215? The number in the tenths place is 4, which is not greater than 5. So, 214.45 becomes 214.00 = 214, no?

 

[MathLover1]

to round 214.45, in the tenths place is 4, which is not greater than 5 , but in the hundredths place is 5, which is = 5, then the tenths place is becomes 5
so, to round it to whole number you get 215
