    Answer:

    52 ft

    Step-by-step explanation:

    area of a square is l x w. all sides are equal so the l = w

    A = 169 ft^2 so each side is the square root of 169 which is 13 ft

    perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

    Perimeter = 13ft × 4 = 52 ft

    so:

    Answer:

    52m

    Step-by-step explanation:

    Area of the square floor = 169 m²

    • For a square with each side ‘s’ , area will be s². Similarly , for a square with area ‘a’ , length of each side will be √a.

    So,

    Length of each side of floor = √169 = 13m

    • For a square with each side ‘s’ , its perimeter will be 4s.

    Hence ,

    Perimeter of the kitchen = 13 × 4 = 52m
