You can put this solution on YOUR website!
i believe the rhombus is a square.
\n" ); document.write( "therefore it's are would be 12^2 = 144.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "why do i believe so?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the opposite angles of a rhombus are equal.
\n" ); document.write( "if one of the angles is 90 degrees than the opposite anglew is 90 degrees and the adjacent angle is 90 degrees and its opposite angle is 90 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that makes it at lesst a rectangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "all sides of a thombus are equal.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that makies it a square.\r
