The advertising area is 32, so the length of the printed part from left to right is 32/x,

The first question:

Column equation: s = 0.5 * x * 2+(32/x+0.5 * 2) *1* 2 = x+64/x+2.

The second question:

X+64/x+2= 18, and the solution is x=8.

That is, the length of the printed part from top to bottom is 8 and the width is 4.

So the length of advertising paper is 8+ 1*2= 10, and the width is 4+0.5*2=5.
