Concept:
The formula for the perimeter of a square with side L is given below as
![P_{\text{square}}=4* L](https://img.qammunity.org/2023/formulas/mathematics/college/okl44fnk1hjuuoek6de7xxrebsc1njpeqn.png)
From the question, the perimeter of the square is given below as
![P_{\text{square}}=4x+24](https://img.qammunity.org/2023/formulas/mathematics/college/ktrackbn88i6sqriog8av9rk0guso9r14g.png)
Step 1: Substitute the expression above in the formula of the perimeter
![\begin{gathered} P_{\text{square}}=4* L \\ P_{\text{square}}=4x+24 \\ \text{Therefore,we will have} \\ 4* L=4x+24 \\ 4L=4x+24 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/6ytgvp6u54jt6l69fxs56g3dmksuvjh7ey.png)
Step 2: Factorize the perimeter 4x+24 by involving brackets
![\begin{gathered} 4L=4x+24 \\ 4L=4((4x)/(4)+(24)/(4)) \\ 4L=4(x+6) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/qxymyx428t7gyfs090b4r9dzci0l3za2h8.png)
Step 3:
To find the value of the length of one side of the square, we will divide both sides by 4
![\begin{gathered} 4L=4(x+6) \\ (4L)/(4)=(4(x+6))/(4) \\ L=x+6 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/h7ks86iqvc4matodp2utrszh6s7pj15zw6.png)
Hence,
The length of one side of the square = x+6
