Explanation:

Step1: Recall perimeter formula for square

The perimeter formula of a square is $P = 4s$, where $s$ is the side - length of the square.

Step2: Substitute the side - length value

Given $s = 19$ feet. Substitute $s = 19$ into the formula $P = 4s$. So $P=4\times19$.

Step3: Calculate the result

$4\times19 = 76$ feet.
