The area of square living room is 169 square feet what is the perimeter of the room

Area of a square = S^2 (S = side length)

to find the length os the side from the area, take the square root of the area:

Side length = sqrt (169)

side length = 13 feet

perimeter of a square is Side length x 4

perimeter = 13 x 4 = 52 feet
