Calculating blocks from given information

Question

I'm confused as to how they calculated the number of blocks from the 220 street and 8 avenues given on the table.

Answer 1

Ok this is super easy with a structure ^^
STRUCTURE RULES: Structure with small numbers such as 1,2,3. Then find the patterns. They apply this to the prompt number. In the long term when you are structured this is very easy.

Column structure
| 1 avenue = 0 block column
|x| 2 avenues = 1 block column
|x|x| 3 avenues = 2 block columns

So n avenue = n-1 block columns

Conclusion
|_|_|_|_|_|_|_| 8 avenues = 7 block columns

Row structure
_ 1 street = 0 block row
_
x 2 streets = 1 block row
_
x 3 streets = 2 block rows
x

So n street = n-1 block rows

Conclusion
220 streets = 219 block rows

Block structure
_
|x| 2 avenues x 2 streets = 1 column x 1 row = 1 block
__
|x|x| 3 avenues x 2 streets = 2 columns x 1 row = 2 blocks
__
|x|x|
|x|x| 3 avenues x 3 streets = 2 columns x 2 rows = 4 blocks

so 8 avenues x 220 columns = 7 avenues x 219 columns = 1533 blocks

Answer 2

Honestly?

This is a pretty crazy question! I cannot see this question being on a real case.

Rather, they would just expect you to multiply 220 by 8.
