Answer 1

@brainzonly

Answer 2

n x m

Answer 3

That would only work if it is a 1 by n board.

Answer 4

Oh number of squares woops >.<

Answer 5

For instance, in an 8 by 8, there is a 204 squares. But I don't know how to find the squares in boards with 5 by 8 or 9 by 3.

Answer 6

Oh I see, you're including all of the larger squares. hmm

Answer 7

Multiply! 5*8=?

9*3=?

Answer 8

No, but if I multiply, thats only going to give me the 1 by 1 squares. There are still bigger ones @mathmale

Answer 9

I'm not familiar with this type of problem.
How did you find the squares in the 8 by 8?
Am I understanding the pattern correctly?
You added the first 8 perfect square values?

Answer 10

Wouldn't an 8 row by 8 column board have 8*8 = 64 squares?

Answer 11

For the 8 by 8, you are supposed to do 8^2 + 7^2 + 6^2 + 5^2 + 4^2 +3^2 + 2^2 + 1^1 = 204

Answer 12

The 2x2 has 5 squares in it.
Four 1x1 squares,
One 2x2 square.

We're including the larger shapes :)
