area of rhombus is 1/2 the product of the diagonals\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let x=diagonal, so 2x+1=\"other diagonal\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(1/2)(x)(2x+1)=7.5 ... 2x^2+x=15 ... 2x^2+x-15=0 ... (2x-5)(x+3)=0
\n" ); document.write( "
\n" );
