Answer:
Jason need to trim is 65 feet
Step-by-step explanation:
We are given
The room is 14 feet wide and 20 feet long
so, length is 20 feet
[tex]L=20[/tex]
width is 14 feet
so, [tex]W=14[/tex]
now, we can find perimeter
P=2L+2W
[tex]P=2\times 20+2\times 14[/tex]
[tex]P=68[/tex]
There is a door opening that is 3 feet wide
So, Jason need to trim
=68-3 feet
=65 feet
