The US dollar bill is 2.6" by 6.1". So in terms of width, 20.5/6.1 = 3.36 dollar bills can fit along one side of the wall. In terms of height, 37/2.6 = 14.23 dollar bills can fit along the other side of the wall. I'm rounding up to 4 dollar bills in width and 15 for height (some will need to be cut). So for the whole area, 4*15 = 60 dollar bills total.
