Answer 2

The height of a parallelogram is "14 cm" and base is "28 cm".

Step-by-step explanation:

$Let \ the \ height \ of \ parallelogram \ be \ "x".\\And,the \ base \ of \ parallelogram \ be \ "2x".\\Area=392 \ cm^2\\\\As \ we \ know,\\\\Area \ of \ parallelogram,\\A=base\times height\\\\On \ putting \ the \ values ,we \ get\\\\392=2x\times x\\\\392=2x^2\\\\x^2=\frac{392}{2}\\ \\x^2=196\\\\x=\sqrt{196}\\ \\x=14\\\\Now,\\The \ height \ of \ parallelogram=14 \ cm\\The \ base=2\times 14=28 \ cm$
