Answer:

44 ft

Step-by-step explanation:

step 1

Find the length side of the square box

The area of the box is equal to

A=b^{2}

where

b is the length side of the square box

we have

A=121\ ft^2

substitute

121=b^{2}

solve for b

square root both sides

b=11\ ft

step 2

Find the perimeter of the square box

The perimeter of the square box is

P=4b

we have

b=11\ ft

substitute

P=4(11)=44\ ft
