**Step 1: Write the equation for the perimeter.**

The total perimeter is given by the sum of all sides. If the missing side is $$ x $$, the equation is:

$$
17 + 52 + 18 + 29 + x = 256
$$

**Step 2: Compute the sum of the given sides.**

$$
17 + 52 = 69
$$
$$
69 + 18 = 87
$$
$$
87 + 29 = 116
$$

So, the sum of the known sides is $$ 116 $$ feet.

**Step 3: Solve for $$ x $$.**

Substitute the sum into the equation:

$$
116 + x = 256
$$

Subtract $$ 116 $$ from both sides to find $$ x $$:

$$
x = 256 - 116 = 140
$$

**Final Answer:** The missing side is $$ 140 $$ feet.
The missing side is 140 feet.
