Given:
Perimeter of the figure = 18.6 inches
To find:
The length of n.
Solution:
Perimeter of the figure = 18.6 inches
Perimeter = Sum of the sides
3 + 6.3 + 4.5 + n = 18.6
13.8 + n = 18.6
Subtract 13.8 from both sides.
13.8 + n - 13.8 = 18.6 - 13.8
n = 18.6 - 13.8
n = 4.8
The length of n is 4.8 inch.
I would say 2.5 because that would be exactly in the middle
The amount of different ways possible can be shown by 7!=5040 Im pretty sure.
