    Answer:

    • 48 units

    Step-by-step explanation:

    Perimeter is the sum of the side lengths

    If polygon A has perimeter

    • P  = a+b+c+d for example

    Then polygon B has perimeter of

    • P’ = 1/3a+1/3b+1/3+1/3d = 1/3P as each side is 3 times smaller than the corresponding side

    Since P = 144

    • P’ = 1/3P = 1/3*144 = 48 units

    We can write a ratio comparing the sides of both polygons.

    A:B = 3:1

    Since we know that 144 is the perimeter for polygon A, we can substitute it.

    144:B = 3:1

    ~Simplify

    144 = 3B

    Divide 3 to both sides

    48 = B

    Therefore, the perimeter of B is 48 units.

    Best of Luck!
