Answer:
Option C is correct
76 feet
Step-by-step explanation:
Area of square(A) is given by:
\(A =s^2\)
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;
\(s^2 = 360\)
⇒\(s = \sqrt{360} =18.973666\)
Perimeter(P) of square is given by:
\(P = 4s\)
then;
\(P = 4 \cdot 18.973666 = 75.894664 \approx 76 ft\)
Therefore, 76 feet molding does he need.
