Answer:
8 nickels and 14 quarters
Step-by-step explanation:
 
        
             
        
        
        
The perimeter of a square is the sum of its sides and they
are all equal, so to obtain the length of each of them we divide the perimeter
of the first fence between 4:
 P1= 64 feet/4 sides
 P1= 16 feet
 Then, the length of each side of the second fence will
increase 2 feet at each end, as shown in the figure. We have then that the
perimeter of the second fence is:
 P2 = 20 feet x 4 sides
 P2 = 80 feet
 The sum of the perimeters of both fences is:
 PT = P1 + P2
 PT = 64 feet + 80 feet
 PT = 144 feet
 Total cost = 1.17 $ x 144 feet
 Total cost = 168.48 $
 The total cost of the fences was $ 168.48
