If that's 395.64 square units, it rounds to 396. If it's something else, you should tell us what it is.
if you round to nearest unit, it is 3.
To find the nearest square unit of a given area, first calculate the square root of the area to determine the side length of the square. Round this side length to the nearest whole number, then square that rounded value to find the nearest square unit. For example, if the area is 20, the square root is approximately 4.47, rounding to 4 gives a nearest square unit of 16 (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.
