If the area of a rhombus is 252 and the perimeter is 84, what is the altitude?
\n" ); document.write( "

\r\n" );
document.write( "The perimeter 84 is the sum of all 4 sides.  Since a rhombus has 4 equal sides,\r\n" );
document.write( "each side is  of 84 or 21 each:  \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Draw the altitude (in green), label it h:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The area of a parallelogram (and a rhombus IS a parallelogram) is\r\n" );
document.write( "\r\n" );
document.write( "Area = base×altitude\r\n" );
document.write( "\r\n" );
document.write( "The base is the bottom side or 21, the altitude is h and the area is 252.\r\n" );
document.write( "\r\n" );
document.write( " 252 = 21×h\r\n" );
document.write( " \r\n" );
document.write( "  = h\r\n" );
document.write( "  12 = h\r\n" );
document.write( "\r\n" );
document.write( "So the altitude is 12.\r\n" );
document.write( "\r\n" );
