We have been given that Ben has a square garden that has sides measuring X feet, Ben wants to increase every side of his garden by 11 feet in order to plant more vegetables. So each side of garden would be
.
We are also told that after Ben increased his garden it will have a perimeter of 104 feet.
We know that perimeter of square is 4 times the side length. So perimeter of garden after enlargement would be
.
Now we will equate perimeter of new garden with 104 as:
![4(X+11)=104](https://img.qammunity.org/2021/formulas/mathematics/college/939s6vj8wm2wifmxh6kmtewutuc8pheapc.png)
Therefore, the equation
can be used to solve for X.
![(4(X+11))/(4)=(104)/(4)](https://img.qammunity.org/2021/formulas/mathematics/college/i16fu8hnxmcxqnz5f0xjo48981f5s3z8s0.png)
![X+11=26](https://img.qammunity.org/2021/formulas/mathematics/college/7bgqyc98cgxxkbd0evfli0knz4czc8k43a.png)
![X+11-11=26-11](https://img.qammunity.org/2021/formulas/mathematics/college/16maxeahid8dg0q73rt9a1ypep5g1nf1xp.png)
![X=15](https://img.qammunity.org/2021/formulas/mathematics/college/vr8l52lyqtbripr5twunzbma6rqd0ups8e.png)
Therefore, the value of X is 15 feet.
