Well, darling, an A3 piece of paper measures 29.7 x 42.0 centimeters. It's like the Goldilocks of paper sizes - not too big, not too small, just right for your printing needs. So go ahead, print that masterpiece and show the world what you've got!
1 m = 100 cm 1 sq m = 1 m x 1 m = 100 cm x 100 cm = 10000 sq cm ⇒ 0.01 sq m = 0.01 x 10000 sq cm = 100 sq cm A C7 envelope (big enough to hold a piece of A7 paper, or A6 paper folded in half, or A5 folded in quarters) is 8.3 cm by 11.2 cm which has an area of 8.3 cm x 11.2 cm = 92.2 sq cm. It should be quite possible to write your name and address on a piece of paper with an area of 0.01 sq m = 100 sq cm, for example a piece of paper 10 cm by 10 cm. Now that I've written my name and address on a piece of paper 10 cm by 10 cm, what should I do with it?

20 cm² represents an area measurement, equivalent to a square that is 4 cm on each side. It can also be visualized as a rectangle measuring 10 cm by 2 cm. In practical terms, it's a relatively small area, comparable to the size of a standard piece of paper.

The area of a rectangle is calculated by multiplying its length by its width. For a piece of paper measuring 21 cm by 15 cm, the area is 21 cm × 15 cm, which equals 315 square centimeters.
