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:
i. 4∈C => False
ii. 5∈C => True
iii. A = B => False
iv. B=C => True
Step-by-step explanation:
Given sets are:

Lets look at the statements one by one.
<u>i. 4∈C</u>
This statement means that 4 is a member of set C. Looking at the members of set C, it can be concluded that the statement is wrong as C doesn't contain 4.
<u>ii. 5∈C</u>
This statement is true as 5 is a member of C.
<u>iii. A=B</u>
This statement states that set A is equal to set B. Two sets are said to be equal if there number of elements and members are same. Set A and Set B have different members so this statement is false.
<u>iv. B=C</u>
Set B and Set C have equal number of members and the members (5,6,2) are also same so the statement is true.
Hence,
i. 4∈C => False
ii. 5∈C => True
iii. A = B => False
iv. B=C => True
