Question

What units are used when talking about area

Answer 1

Every unit of length has a corresponding unit of area, namely the area of a squarewith the given side length. Thus areas can be measured in square metres (m2), square centimetres (cm2), square millimetres (mm2), square kilometres (km2), square feet (ft2), square yards (yd2), square miles (mi2), and so forth.

so, to shorten it down, its a little number 2.

Answer 2

The unit depends on the question (feet, inches, yards, meters etc). But with area it's the unit squared like if it was feet it would be ft²
