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.

Step-by-step explanation:
The principal Marshall invested is $4500.
The rate of interest is 6%
The compound interest formula is

We substitute P=4500,r=0.06 and t=5 to obtain:

We simplify to get:

This gives us:

The interest after 5 years is
