oh, sorry my answer is wrong :) you can follow the other comment.
The formula of a perimeter of rectangle:
P = 2(w + l)
We have l = 12 in and P = 56 in.
Substitute:
2(w + 12) = 56 <em>use distributive property</em>
(2)(w) + (2)(12) = 56
2w + 24 = 56 <em>subtract 24 from both sides</em>
2w = 32 <em>divide both sides by 2</em>
w = 16
<h3>Answer: D. 16 in.</h3>
