The bathroom wall in the figure, which is rectangular in shape, will be completely covered with identical yellow and blue rectangular tiles of the same dimensions, with no gaps between the tiles. This covering process will be completed by using, as shown in the figure, one row of yellow tiles followed by one row of blue tiles, in sequence. When the covering process is completed, the ratio of the area covered by yellow tiles to the area covered by blue tiles has been calculated as $\frac{3}{4}$. Accordingly, what is the total number of tiles on this wall? A) 56 B) 63 C) 70 D) 77 E) 84
