To find the length of each side of a square garden given its area, you can use the formula for the area of a square:
\[ \text{Area} = \text{side}^2 \]
In this case, the area is 205 square feet. To find the length of each side, you take the square root of the area:
\[ \text{side} = \sqrt{205} \]
Calculating the square root:
\[ \text{side} \approx 14.32 \text{ feet} \]
Therefore, the approximate length of each side of the garden is 14.32 feet.
