Question

find the perimeter. simplify your answer.

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a square (since all sides are of length $y$) is the sum of the lengths of all its sides. For a square with side - length $s$, the formula is $P = 4s$.

Step2: Substitute side - length

Here, $s=y$. So, $P = 4\times y=4y$.

Answer:

$4y$
