PLEASE HELP ANYONE WHO IS GOOD AT MATH!!!!

Answer 1

Answer:

A is the correct answer sqrt 200. The answer to the second part of the question is C. 10 sqrt 2

Step-by-step explanation:

Answer 2

1. Let the side length of the foundation be x.

2. The area of any square-shaped region = area of square = side length squared.

3. So $x^{2} (ft^{2}) =200(ft^{2})$
         $x^{2} =200$

take square root of both sides, to isolate x:
         
         $\sqrt{x^{2} }= \sqrt{200}$

                  $x= \sqrt{200}$ (ft)
