    Please I really need clarifications with the wording of this question.

    when you say a 3x2 grid, I am thinking a grid with 3 rows and 2 columns and I cant see that here.

    Also it says "There are 5 grids smaller than 3x2, vertical and horizontal dimensions being important....",5 grids smaller? Please how do you define a grid ?

    Also where the problem said "Adding those to the 37 of the 3x2 grid, a total of 72 different rectangles" ... how did 72 come about. I can just think of 37 + 18 = 55.
