204 square feet of floor space means the area is 204 square feet. Area is equal to the length (l) times the width (w) or A = l * w.
Since you know A equals 204 ft2 and l equals 17 ft, you just have to solve for w.
204 ft2= 17 ft * w ft
Divide both sides by 17 to get 204 ft2/17 ft = w ft
Thus w = 12 ft.
