B.
This is because perpendicular lines have opposite and flipped slopes.
Using the perimeter of a rectangle, it is found that she can make a deck of 122 ft wide.
<h3>What is the perimeter of a rectangle?</h3>
The perimeter of a rectangle of length l and width w is given by:

In this problem:
- She has enough wood to build a deck that is 280ft, hence P = 280.
- The length is of 10 feet, hence l = 10.
- Considering that the deck's width will be added to the actual width of 8 feet, we have that w = 8 + w.
Then:






She can make a deck of 122 ft wide.

Hello.
JK (or any other combination of letters) doesn't stand for anything in geometry. The purpose of these letters is to reference certain angles and sides of a figure without having to describe the angles/sides in relation to other angles/sides to know exactly which angle or side is being referenced.
Hope this helps!
