Answer:
Option C is correct
76 feet
Step-by-step explanation:
Area of square(A) is given by:
[tex]A =s^2[/tex]
where, s is the side of the square.
As per the statement:
A square ceiling has an area of 360 square feet.
⇒A = 360 square feet.
then;
[tex]s^2 = 360[/tex]
⇒[tex]s = \sqrt{360} =18.973666[/tex]
Perimeter(P) of square is given by:
[tex]P = 4s[/tex]
then;
[tex]P = 4 \cdot 18.973666 = 75.894664 \approx 76 ft[/tex]
Therefore, 76 feet molding does he need.
