The perimeter of a pool table is 30 ft. The table is twice as long as it is wide. What is the length of the pool table?

  • Math -

    P = 2(L + W)

    Half of 30 is 15.

    Take it from there.

  • Math -

    perimeter is adding up all sides so x equals the width and 2x equals the length. x+x+2x+2x=30. so 6x=30, divide 30 by 6= 5, so x=5 which is the width and 2x=10 which is the length.

  • Math -

    I don't get what l and w would be

  • Math -

    P = 2(L + W)

    30 = 2 (2W + W)
    30 = 4W + 2W
    30 = 6W
    30/6 = W
    5 = W

    Now find the length.
