Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a parallelogram with adjacent - side lengths $a$ and $b$ is $P = 2(a + b)$. In a parallelogram, opposite sides are equal. Here, the adjacent - side lengths are both 54.

Step2: Substitute values into formula

Substitute $a=b = 54$ into the formula $P=2(a + b)$. We get $P = 2(54+54)$.

Step3: Simplify the expression

First, calculate $54 + 54=108$. Then, $2\times108 = 216$.

Answer:

216
