10 cm = 0.1 meter
20 cm = 0.2 meter
Each block covers (0.1 x 0.2) = 0.02 square meter.
To cover 12 square meters, you need 12/0.02 = 600 blocks.
A square meter is 100x100 which means there are 10000 sq cm in a sq meter. Your blocks are 450mmx450mm which means that they are 45cm x 45 cm 45x45=2025 10000/2025= 4.94 paving flags. However, you might want to calculate the amount of blocks needed for the entire area you're paving, not for each meter. Always remember to round up and leave yourself some extras, Keep in mind that you may need to leave some gap between the blocks, and that doing so may help you use fewer blocks. For example if you are paving an ally a meter wide, then leaving a gap of three centemeters at the sides of the ally and three centemeters betweed the blocks will mean you get away with using two blocks width and don't need to cut any blocks (which would be a pain in the neck).
25 such blocks to equal one square metre.
4.94 per sq meter so rounded up to 5 per sq meter
A standard block is 440mm x 215mm x 100mm you will require 10 blocks per square metre.

There are 10 blocks in a square meter
It depends on the size of the concrete blocks

The answer will depend on the orientation of the blocks. It will be between 13 and 25.
25 such blocks to equal one square metre.
The answer will depend on the size of the blocks.
60 blocks make a metre square
Depends entirely on the size of the individual blocks !

What sort of blocks? Childrens' building blocks? If so, how big is each block?
4.94 per sq meter so rounded up to 5 per sq meter
