In looking at this problem, the answer has already been stated in the problem itself.
Now, because the area is 40 square inches and the grid for the paper is 1 inch (square), then the drawing would use 40 squares.
The other consideration would be at length and width of the drawing which could change according to how she did the drawing on the paper.
