Answer:
Perimeter = 2x + 64
Step-by-step explanation:
Perimeter = Sum of the lengths of the borders
From the given figure, we need to find the missing length.
Missing length = 18 - 10 = 8
Another missing length = (x + 14) - (x + 8) = x + 14 - x - 8
= 14 -8
= 6
Now let's add all the sides.
Perimeter = x + 14 + 8 + 6 + 10 + x + 8 + 18
Now add all the x terms and constants
Perimeter = 2x + 64
