Answer:

To find the value of x, we need to add up all the sides of the shape and set them equal to the perimeter:

x + 9 + x + 2 + x + 6 + 2x - 4 = 94

Combining like terms, we get:

5x + 13 = 94

Subtracting 13 from both sides, we get:

5x = 81

Dividing both sides by 5, we get:

x = 16.2

Therefore, the value of x is 16.2 cm.
