Answer:
24x
Step-by-step explanation:
The total length of all vertical segments is 5x·2 = 10x.
The total length of all horizontal segments is (3x+4x)·2 = 14x.
Then the total length of all perimeter segments is ...
10x +14x = 24x . . . . perimeter of the figure
Check the picture below.
so notice, their perimeter is the same, because the perimeter is just one rod anyway, and all rods are the same length, thus
-66 divided by 7 equals -9.43
