Answer:
11 feet
Explanation:
The area of a square is calculated using the following formula:
A = s²
where:
- A is the area of the square
- s is the length of a side of the square
We know that the area of the garden is 121 ft², so we can set up the following equation:
121 = s²
To solve for the length of a side of the garden, we can take the square root of both sides of the equation.

s = 11 ft
Therefore, each side of the garden is 11 feet long.
