To find the perimeter of a square, you can use the formula:
\[ \text{Perimeter} = 4 \times \text{side length} \]
Given that the side length of the square is 29 inches, the calculation would be:
\[ \text{Perimeter} = 4 \times 29 \text{ in} = 116 \text{ in} \]
So, the perimeter of the square is 116 inches.
