1 : 5*5
4 : 4*4
9 : 3*3
16 : 2*2
25 :1*1
sum(i=1 to 5; i^2) = (25 + 16 + 9+ 4+ 1) = 55
Good Luck.

In general an N x N checkerboard has total number of squares equal to the sum 1 + 4 + 9 + 16 + ,,, of the first N perfect squares. This is equal to
N (N+1) (2N + 1) / 6
squares. In your situation,
5 * 6 * 11 / 6 = 55.
Oh and Sarah_dream_act... 55 is not a stupid answer, it is the correct one :) We call that "thinking outside the box".

There is 1 5x5 square.
There are 4 4x4 squares.
There are 9 3x3 squares.
There are 16 2x2 squares.
There are 25 1x1 squares.
Thus there are 55 squares in total

9 morons to 3 sensible answers (at the last count) is about par for this course! (I suspect that one answer was simply copied from above).
There are 55 squares (of sizes ranging from 1 unit to 5), of course.
Now, how many rectangles?

Checkerboards have 64 squares. It doesn't matter what size the board measures- if it is a checkerboard it will have 64 squares.
