please i'm about to fail

Answer 1

Answer: the perimeter of the square is 44

Answer 2

44 ft

Explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

Here A = 121, thus

s² = 121 ( take the square root of both sides )

s =
`√(121)` = 11

Perimeter = 4 × 11 = 44 ft
