Question

Complete the table with the perimeter of a square for each given side length. Recall all 4 sides of the square are equal. side length (inches) perimeter (inches) 0.5 7 20

Answer 1

The formula to find the perimeter fiven the side length is:

$p=4\times l$

For the square with side 0.5:

$\begin{gathered} l=0.5 \\ \text{substituting this value into the perimeter formula:} \\ p=4\times0.5 \\ p=2in \end{gathered}$

For the square with side 7:

$\begin{gathered} l=7 \\ \text{substituting this value into the perimeter formula:} \\ p=4\times7 \\ p=28in \end{gathered}$

For the square with side 20:

$\begin{gathered} l=20 \\ \text{substituting this value into the perimeter formula:} \\ p=4\times20 \\ p=80in \end{gathered}$
