Question

Define a variable and write an equation to model the situation

Answer 1

D.

We were given that:

Perimeter (square) = 4 times the length of a side

For a square, all its sides are congruent

`\begin{gathered} Perimeter_(square)=4* length \\ \text{Let the length be represented by ''s'', the expression becomes:} \\ length=s \\ Perimeter_(square)=4* s \\ Perimeter_(square)=4s \\ \\ \therefore p=4s \end{gathered}`

Therefore, the correct option is D.
