B. 26 Feet
C. 39 Feet
D. 44 Feet

The perimeter of the fencing is 44 feet (Option D)

Step-by-step explanation:

Area and Perimeter

A square shape of side length (a) has an area given by:

And its perimeter is calculated as:

P = 4a

The area of Katrina's square garden is given as A=121 square feet. We need to calculate the side length by solving for a:

a = 11 feet

Once we know the value of a, then we calculate the perimeter:

P = 4*11 = 44

The perimeter of the fencing is 44 feet (Option D)

10.416 meters per second
