The perimeter of the hall is the sum of its side lengths.
The perimeter of the museum exhibit hall is 240 feet
<h3>How to determine the perimeter</h3>
From the question, we understand that the shape of the museum exhibit hall is a regular octagon
The perimeter of a regular octagon is:
p = 8l
Where l represents the side length of the octagon
So, we have:
p = 8 * 30 feet
Evaluate the product
p = 240 feet
Hence, the perimeter of the exhibit hall is 240 feet

Answer:
The maximum profit is reached with 4 deluxe units and 6 economy units.
Step-by-step explanation:
This is a linear programming problem.
We have to optimize a function (maximize profits). This function is given by:

being D: number of deluxe units, and E: number of economy units.
The restrictions are:
- Assembly hours: 
- Paint hours: 
Also, both quantities have to be positive:

We can solve graphically, but we can evaluate the points (D,E) where 2 or more restrictions are saturated (we know that one of this points we will have the maximum profit)

The maximum profit is reached with 4 deluxe units and 6 economy units.
The answer is A. 3
