Let length = \"+L+\"
\n" ); document.write( "Width = \"+2L+-+1+\"
\n" ); document.write( "\"+L%2A%28+2L+-+1+%29+=+63+\" cm2
\n" ); document.write( "\"+2L%5E2+-+L+-+63+=+0+\"
\n" ); document.write( "\"+L+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"+L+=+%28-%28-1%29+%2B-+sqrt%28+%28-1%29%5E2-4%2A2%2A%28-63%29+%29%29%2F%282%2A2%29+\"
\n" ); document.write( "\"+L+=+%28+1+%2B-+sqrt%28+1+%2B+504+%29%29%2F4+\"
\n" ); document.write( "\"+L+=+%28+1+%2B+22.472+%29%2F4+\"
\n" ); document.write( "\"+L+=+23.472%2F4+\"
\n" ); document.write( "\"+L+=+5.868+\"
\n" ); document.write( "Width = \"+2%2A5.868+-+1+\"
\n" ); document.write( "Width = \"+10.736+\"
\n" ); document.write( "Let \"+d+\" = the length of the diagonal in cm
\n" ); document.write( "\"+d%5E2+=+5.868%5E2+%2B+10.736%5E2+\"
\n" ); document.write( "\"+d%5E2+=+34.4334+%2B+115.2617+\"
\n" ); document.write( "\"+d%5E2+=+149.6951+\"
\n" ); document.write( "\"+d+=+12.235+\" cm
