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* l`

For the square with side 0.5:

`\begin{gathered} l=0.5 \\ \text{substituting this value into the perimeter formula:} \\ p=4*0.5 \\ p=2in \end{gathered}`

For the square with side 7:

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

For the square with side 20:

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