Answer 1

Hope this will help you

Answer 2

The altitude of parallelogram is "14 cm".

Step-by-step explanation:

$Let \ the \ base \ of \ parallelogram \ be \ "x".\\and,the \ altitude \ be \ "2x".\\The \ Area=98 \ cm^2\\\\As \ we \ know,\\\\The \ Area \ of \ parallelogram,\\A=base\times altitude\\\\On \ putting \ the \ values \ in \ the \ above \ formula,we \ get\\\\98=x\times 2x\\\\98=2x^2\\\\x^2=\frac{98}{2} \\\\x^2=49\\\\x=\sqrt{49}\\ \\x=7\\\\Now,\\The \ base \ of \ parallelogram=7 \ cm\\The \ altitude \ of \ parallelogram=2\times 7=14 \ cm$
