To find the perimeter of a square, you can use the formula:
\[ \text{Perimeter} = 4 \times \text{side length} \]
In this case, if the side length of the square is 14 feet, the calculation for the perimeter will be:
\[ \text{Perimeter} = 4 \times 14 , \text{ft} = 56 , \text{ft} \]
Thus, the perimeter of the square is 56 feet.
