Answer:
Part a: The number of ways in which the candidates can be appointed on the executive posts are 11880.
Part b: The number of ways in which the candidates can be appointed as members of the planning committee are 495.
Step-by-step explanation:
As the complete question is not given a similar question is found online and is attached herewith.
Part a: Number of ways in which 12 candidates can be appointed for President, Chief Executive Officer, Chief Operating Officer and Chief Finance Officer.
Number of Candidates=12
Number of Posts=4
As the order is important the number of ways are identified using Permutations given as

So the number of ways in which the candidates can be appointed on the executive posts are 11880.
Part b: Number of ways in which 12 candidates can be appointed as members of the planning committee.
Number of Candidates=12
Number of Posts=4
As the order is not important the number of ways are identified using Combinations given as

So the number of ways in which the candidates can be appointed as members of the planning committee are 495.
If one square takes 16.4 cm of wire, this means that to form 25 identical squares you need 25(16.4) cm of wire = 410 cm
To convert this to m you just need to divide it by 100 because there are 100 cm in one meter = 4.1 m
Therefore your final answer is: You need 4.1 m of wire to form 25 squares, each with a perimeter of 16.4 cm.
Step-by-step explanation:
since all 4 sides are equal in length, the figure is a square.
let the length of the square be lm.
529 = l x l
l = 23m
perimeter = 23 x 4 = 92m
