it depends on your object.
if your object is a triangle the area in square units is .5base times hieght
if your object is a circle the area in square units is pi time radius squared
if your object is a rectangle the area in square units is length times width
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).
