The width of the construction paper is 12 inches.
The formula for area is length(l)*width(w)=area in units squared(a^2).
To find the width, we divide both sides by length, this gives us the following:
17*w=204in^2 w=204in^2/17
To find the answer, you just perform the operation.
204/17=12
The width is 12 inches.
