Question

why is the unit of area expressed in square centimetres

Answer 1

Answer:

because we are multiplying the two things so while multiplying only 8n case of area the unit will also get multiplied... unit square.

Answer 2

Answer:

Calculation of the area of a square whose length and width are 1 metre would be:

1 metre × 1 metre = 1 m2

and so, a rectangle with different sides (say length of 3 metres and width of 2 metres) would have an area in square units that can be calculated as:

3 metres × 2 metres = 6 m2. This is equivalent to 6 million square millimetres. Other useful conversions are:

1 square kilometre = 1,000,000 square metres

1 square metre = 10,000 square centimetres = 1,000,000 square millimetres

1 square centimetre = 100 square millimetres.
