I don't really understand what are you trying to achieve but i supose you want to tile the background ; you just need to take one tile
here the pixels coordinates
position in the sprite sheet :
w:16/h:119 /right top corner
w:22/h:119 /left top corner
w:16/h:151 /right bottom corner
w:22/h:151 /left bottom corner
size of one tile(selected in the picture):
7:33 pixels
or if you don't need the 3 pixels above
position in the sprite sheet :
w:16/h:122 /right top corner
w:22/h:122 /left top corner
w:16/h:151 /right bottom corner
w:22/h:151 /left bottom corner
size of one tile(selected in the picture):
7 by 30 pixels
