The perimeter of the hall is the sum of its side lengths.
The perimeter of the museum exhibit hall is 240 feet
How to determine the perimeter
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
