We are given that the area of a square is 52 square feet. To determine the side length we need to have into account the formula for the area of a square, that is:
[tex]A=l^2[/tex]
Where "l" is the side length and "A" is the area. Solving for "l" by taking square root on both sides:
[tex]\sqrt[]{A}=l[/tex]
Replacing the value of "A":
[tex]\sqrt[]{52ft^2}=l[/tex]
Solving the operations:
[tex]7.2ft=l[/tex]
Therefore, the point that best represents the side length is the second point from left to right, that is, point B.
