The width of the rectangle is [tex]\boxed{16}[/tex] cm^2.

[tex]\rm Explanation:[/tex]
Formula for area is:
A = l × w
We know that we must multiply the length by the width to find the area.
Since we want to find one of the rectangle's dimensions, and not the area, we'll use the opposite operation.
What's the opposite of multiplication? Division!
-------------------------------------------------------
Divide the area of the rectangle by its length to find the width:
W = A ÷ l
W = 192 ÷ 12
W = 16
