    let's x be the shortest piece

    the middle piece is 1,73 * x

    the longest piece is 3,09 x

    then if we sum the 3 pieces we will get the steel rod that is 64 feet long

    so x+1,73x+3,09x = 5,82x = 64 then x = 10,99 = 11

    the shortest piece is 11 feet

    the middle piece is 1,73*11=19,03 feet

    The longest piece is: 3,09*11 = 33,99 = 34 feet
