    What do you mean by "best?" Is it a long narrow pen so that the dog can run? Or is a pen with the most square feet?

    problem problem just says rectangular dog ben nothing about squar feet so i am assuming so that the dog has the most room

    You might try a few possible dimensions to see which produces the largest pen.

    A = 2L + 2W

    A = 2(3) + 2(9)

    A = 2(4) + 2(8)

    A = 2(6) + 2(6)

  • Geometry -

    A = 2(4) + 2(8)
    8 + 16 = 24
    then you would divide the 8 and the 16 by 2 giving the dimensions

    4 4 8 8 =24

    is this correct

  • Geometry -

    Right that would produce a pen that was 4 feet wide and 8 feet long. It would contain 32 square feet.

    However a square pen that was 6 feet on each side would have an area of 36 square feet.
