a rhombus has a perimeter of 84 cm and an area of 252 cm square.find the lenght of the altitude
\n" ); document.write( ".
\n" ); document.write( "Since all sides are equal, the length of one side is:
\n" ); document.write( "84/4 = 21 cm
\n" ); document.write( ".
\n" ); document.write( "area = (1/2)ba
\n" ); document.write( "252 = (1/2)(21)a
\n" ); document.write( "504 = (21)a
\n" ); document.write( "504/21 = a
\n" ); document.write( "24 cm = a (altitude)
\n" ); document.write( "
\n" ); document.write( "
