    Answer: Perimeter = 42.2 m

    Area = 81.1125 m²

    Step-by-step explanation:

    Lower Upper

    Length is given as 15.8 - -> 15.75 ≤ L < 15.85

    width is given as 5.2 - -> 5.15 ≤ w < 5.25

    Perimeter = 2L + 2w (Upper bound)

    = 2 (15.85) + 2 (5.25)

    = 31.7 + 10.5

    = 42.2

    Area = Length x width (Lower bound)

    = 15.75 x 5.15

    = 81.1125
