The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
Area = pi*7.12 = 158.3676857 or 158 square m
Using Pythagoras' theorem and the area formula it is: 167 square cm to the nearest unit.
42.1 rounded to the nearest unit or nearest one is 42.
Suppose you had a rectangle that was 12.75 units by 19.6 units. The area would be 249.9 square units which would round to 250 square units to the nearest square unit. Since a centimeter isn't a square unit, it can't be rounded to the nearest square unit.

If that's 28.2743 square units, it rounds to 28.
Rounded to the nearest unit, the area of Cambodia is 69,898 square miles.
50.4 rounded to the nearest whole number is 50. Since a square foot is a unit of area measurement, 50 square feet would be the nearest square foot approximation for this value.
If that's 75.8 square units, it's already there.

Using Pythagoras' theorem and the area formula it is: 167 square cm to the nearest unit.
It means that you read to the nearest number. For example: 15.765 is rounded to 16. Another example: 12.323 is rounded to 12.
If that's 395.64 square units, it rounds to 396. If it's something else, you should tell us what it is.
