Answer:
The unknown dimension is 35
Step-by-step explanation:
The perimeter of a rectangle is l+l+w+w or 2l+2w (l=length, w=width)
![l+l+w+w=84](https://tex.z-dn.net/?f=l%2Bl%2Bw%2Bw%3D84)
![7+7+w+w=84](https://tex.z-dn.net/?f=7%2B7%2Bw%2Bw%3D84)
![14+w+w=84](https://tex.z-dn.net/?f=14%2Bw%2Bw%3D84)
then we subtract 14 from 84
![w+w=70](https://tex.z-dn.net/?f=w%2Bw%3D70)
![2w=70](https://tex.z-dn.net/?f=2w%3D70)
![\frac{70}{2}=35](https://tex.z-dn.net/?f=%5Cfrac%7B70%7D%7B2%7D%3D35)
Let's check our answer
![35+35+7+7=84](https://tex.z-dn.net/?f=35%2B35%2B7%2B7%3D84)
<u>Hope this helps :-)</u>
