The table shows the side lengths and perimeters of four squares.
\begin{tabular}{|c|c|}
\hline Side Length $(x)$ & Perimeter $(y)$ \\
\hline 4.5 & 18 \\
\hline 8.5 & 34 \\
\hline 10.25 & 41 \\
\hline 13.75 & 55 \\
\hline
\end{tabular}
Which equation represents the relationship between the side length, $x$, and the perimeter, $y$ ?
$y=\frac{1}{4} x$
$y=4 x$
$y=x+13.5$
$y=x-13.5$
Mark this and return
Answer
Thus, the equation that represents the relationship between the side length, $x$, and the perimeter, $y$, is \(\boxed{y=4x}\).
Step 1 ：From the table, we can see that the perimeter of each square is four times its side length.
Step 2 ：This is because the perimeter of a square is calculated by multiplying the side length by 4.
Step 3 ：So, the relationship between the side length, $x$, and the perimeter, $y$, is $y=4x$.
Step 4 ：Thus, the equation that represents the relationship between the side length, $x$, and the perimeter, $y$, is \(\boxed{y=4x}\).
