Do you square the unit at the end of an area equation?

Answer 1

Yes - Is NOT a correct answer.

Is true if the linear units of measure is the units used in the area.

But if the unit of area is singular such as acre, No

In metric, the unit of land measure is Hectacre. So a plot of ground of 100 meters by 100 meters has a area of 10,000 square meters or one Hectacre.

So, the correct answer to this question depends upon the units of measure that you use to express you answer.

The same for volume: If you have a container of 10 cm * 10 cm * 10 cm you can alternately say that the volume is 1000 cubic cm ( Using Cube the Unit ) or One Liter ( Singular Unit of measure )
