Problem 85 (View Problem)

Made nice code to calculate that, but it gives allways false answer (at least problem page says that ).
For debugging help could someone please tell how much rectangles contains 5x4 grid?

It shouldn't be different from brute forcing the 3x2 example that is given by the problem.
Do you get eighteen for the 3x2 grid?

Yes, i get 18 on 3x2 grid.

Ok then, it's 150 rectangles for the 5x4 grid.
Good luck,

Sorry, I got it now. I had to edit the post. Moderators can delete this.

hi trying to get my head round this.

does the rectangle have to have dimensions (n) and (n+/-1) as in the example?

example gives 3*2(area=6) rectangle and 18 as answer.
if i use 6*1(area=6) rectangle 1 get 21 as answer.

could someone tell me if this is correct and is it acceptable?

ie can area=12 be 12*1 or 6*2 or 4*3?

this may just be me being slow, but thanks in advance for any replies.

Any dimension rectangle like the ones you have mentioned are acceptable.

Hello,

Can anyone explain to me why am I getting 816 x 3 as the closest result.
I mean if anyone could check how many rectangles does this size of grid contain?

Your answer is a near miss - it is a just little over 2000000 - but you can get closer.
Remember that you can also get close to 2000000 by being just under it.

Thanks , i really can be dumb sometimes
