not 75, and not 82, but the answer is in between those 2.

yes, very good Jaqueline!, 79 is the answer. I'm impressed.


Jaq's tallied explanation is also correct, she wrote it in the simplified form. below is the longer worded explanation from the website.




There are a total of 79 squares.

How?
Lets assume smallest square side length is 0.5 cms, then
Number of squares with side 0.5 cms: 30
Number of squares with side 1 cms: 16+11
Number of squares with side 1.5 cms: 2 + 3 + 2
Number of squares with side 2 cms: 9 + 1
Number of squares with side 2.5 cms: 0
Number of squares with side 3 cms: 4
Number of squares with side 3.5 cms: 0
Number of squares with side 4 cms: 1
????????????
Thus total number of squares are: 79

ok, so I will post one more. If no one solves it then it shall be the final one posted.

here is the challenge:

1- count all the squares,
2- count all the triangles,
3- subtract the two totals from each other and tell me what the answer is.

and no I do not yet know the answer. I will need to take some time my self to figure it out.

have fun and good luck!

The first 2 puzzles were rather straightforward to resolve as we only needed to create categories(puzzle #1 into colors, puzzle #2 by size.

Puzzle #3 is posing a challenge for me as I am perplexed as to how to approach it. But give me time...

you mean the first 3 puzzles,... and puzzle #4 is posing a challenge. yes? you already solved the first 3.


additionally, in puzzle 4, the squares wont be too bad to count,.. it shall be the triangles that will be difficult to count i think.

Yes, I mean the first 3 puzzles. This is puzzle #4. I stand corrected Zoey... If you could see the stacks of papers and files on my desk you would understand my forgetfulness. That's my story and I'm sticking to it...

And I agree with your opinion regarding the squares. A little clue that is helpful in counting the squares:

If you will shift your vision about 10 degrees...
