297.8 square kilometres.
Now here is a minor digression that you may (or may not) find is of interest:
There are different views on how the digit 5 should be rounded - up or down. 1,2,3 and 4 are always rounded down; 6,7,8 and 9 are always rounded up and 0 does not need rounding. So if you always round 5 down, you will round down 5 numbers and up 4 and so introduce a downward bias in your work. Conversely, if you always round up you will introduce an upward bias. You could randomly decide to round up or down but this makes it more difficult for others to follow what you have done. The recommended answer is to round 5 so that the previous digit is EVEN.
Thus 0.15 is rounded up to 0.2
and 0.45 is rounded down to 0.4
1.90
It ends in a 9, so will round up, leaving 1.90 as the answer.
To round 34279.38 to the nearest kilometer, you look at the digit in the tenths place, which is 3. Since it is less than 5, you round down. Therefore, 34279.38 rounded to the nearest kilometer is 34279 kilometers.

1.90
It ends in a 9, so will round up, leaving 1.90 as the answer.
If it is already square kilometers, it rounds to 1137. If it isn't, it won't round to them.
To round 34279.38 to the nearest kilometer, you look at the digit in the tenths place, which is 3. Since it is less than 5, you round down. Therefore, 34279.38 rounded to the nearest kilometer is 34279 kilometers.
It is 4674 km rounded

Round Length To KM Donald Devine How to round the lenght to the nearest kilometer? You can round a length to the nearest kilometer by using the round() function in Python, along with dividing the length by 1000. Here is an example: Copy code length = 5678 # length in meters rounded_length = round(length / 1000) # divide by 1000 to convert to kilometers and round print(rounded_length) # prints 6 This will round the length of 5678 meters to 6 kilometers.
It is: 10.77 to the nearest hundredth
It is: 4.24 to the nearest hundredth
It ends in a 6, so would round up to give 24 square kilometres.
