$2.3 c m$

#### Explanation:

The area of a rectangle is its length times its width, or $l \cdot w$
You said the area is $12.88 c {m}^{2}$, so we know $l \cdot w = 12.88 c {m}^{2}$
Plugging in the given length, we get $5.6 \cdot w = 12.88$
Dividing both sides by $5.6$ to solve for $w$, we find out that $w = 2.3 c m$.
