The dimensions of the rectangular table are \( \left(2 x^{2}-16\right) \) feet and \( \left(-x^{2}+4 x+1\right) \) feet. Which expression represents the total perimeter of the table, and if \( x=3 \), what is the length of the entire rubber bumper? \( x^{2}+4 x-15 ; 3 \) feet \( x^{2}+4 x-15 ; 6 \) feet \( 2 x^{2}+8 x-30 ; 6 \) feet \( 2 x^{2}+8 x-30 ; 12 \) feet
