Answer:
a = 10.5 feet
Explanation:
Given that,
The area of a square room, A = 110.25 ft²
We need to find the side length of the living room. Let the side be x.
We know that,
The area of a square,
![A=a^2](https://img.qammunity.org/2022/formulas/mathematics/high-school/vtoxpdpiqgyltdr8qo0irf5cr0tzw5hpqg.png)
So,
![a=√(110.25) \\\\a=10.5\ ft](https://img.qammunity.org/2022/formulas/mathematics/high-school/bjfliohfnypglkv6z5b1wfpmhpkv01v6qj.png)
So, the side length of the living room is equal to 10.5 feet.
