Answer:
The value of n is n = 2.56 cm
Option D is correct option.
Step-by-step explanation:
Perimeter of hexagon = 14.7 cm
Five sides have length = n cm
One side has length = 1.9 cm
We need to find value of n
The formula used to find Perimeter of hexagon is : [tex]Perimeter = Sum\;of\:all\:sides[/tex]
We can write:
[tex]Perimeter = Sum\;of\:all\:sides\\14.7=5n+1.9\\[/tex]
Because 5 sides have length = n so, 5n and one side has length = 1.9
Now, solving to find n
[tex]14.7-1.9=5n\\5n=12.8\\n=\frac{12.8}{5}\\n=2.56[/tex]
So, The value of n is n = 2.56 cm
Option D is correct option.
