Answer:
14.46 feet.
Explanation:
We have been given that a squared patio has an area of 209 square feet. We are asked to find the length of each side to the nearest hundredth.
We know that area of a square is the square of its side length. To find the side length of the given squared patio, we will take square root of the area as:
![\text{Area}=\text{Side length}^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/v7neosjdtdka7ry6dk522x5p15ldz11bds.png)
![209\text{ feet}^2=\text{Side length}^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/rlokwzg0fsj3607ttnu04bpm0bp6s0dquo.png)
Switch sides:
![\text{Side length}^2=209\text{ feet}^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/9l1tw03yl5adgvqne0v88loosow59zpw4c.png)
Take square root of both sides:
![\text{Side length}=\sqrt{209\text{ feet}^2}](https://img.qammunity.org/2019/formulas/mathematics/high-school/ogcjk1wdq87h3mukbm1syrx1m41manbacb.png)
![\text{Side length}=14.4568322\text{ feet}](https://img.qammunity.org/2019/formulas/mathematics/high-school/8xjqsn5szmw6rv3mvnnepygkexhbfrcm3y.png)
![\text{Side length}\approx 14.46\text{ feet}](https://img.qammunity.org/2019/formulas/mathematics/high-school/1jl0dj4egz3qk5ncwzmt7eqg8fb4nekxpc.png)
Therefore, the side length of the given square patio is approximately 14.46 feet.
