   @Html.TextAreaFor(model => model.Description, new { @class = "required", style = " rows=10, columns=40" })

Answer 3

Rows and Cols does not come under style tag. Its an independent attribute for textarea. You can write it as below.

@Html.TextAreaFor(model => model.Description, new { @class = "required", @cols = 40, @rows = 10})

Remove textArea element from site.css file. In site.css textarea max-width set as 280px;
Do like

input
,select
/*,textarea*/ 
{
    max-width: 280px;
}
