Let us derive a formula for number of rectangles. If the grid is 1×1, there is 1 rectangle. If it grid is 3×1, there will be 3 + 2 + 1 = 6 rectangles.
How many rectangles are in a 6×6 grid?
Four points, two of which are in the same row and two of which are in the same column, will form the corners of a rectangle. There are = 15 ways to choose any two rows and = 15 ways to choose any two columns, so you can make 15 * 15 = 225 rectangles.

How many rectangles are there in a 5×5 square?
Thus, the number of rectangles in a 5×5 square is the sum of the 1 square wide rectangles in the 1×1, 2×2, 3×3, 4×4, and 5×5 squares or 4 + 18 + 48 + 100 = 170. Therefore, for the typical chess board problem of 8×8 squares, we have a total of 4 + 18 + 48 + 100 + 180 + 294 + 448 = 1092.
