The area of the rectangle is:
\n" ); document.write( "\"A%5Br%5D+=+%284x%2B3%29%283x-2%29\"
\n" ); document.write( "\"A%5Br%5D+=+12x%5E2%2Bx-6\"
\n" ); document.write( "The area of the triangle is:
\n" ); document.write( "\"A%5Bt%5D+=+%281%2F2%29%284x%29%285x%29\"
\n" ); document.write( "\"A%5Bt%5D+=+10x%5E2\"
\n" ); document.write( "\"A%5Br%5D+=+A%5Bt%5D\" so...
\n" ); document.write( "\"12x%5E2%2Bx-6+=+10x%5E2\" Subtract\"10x%5E2\" from both sides.
\n" ); document.write( "\"highlight%282x%5E2%2Bx-6+=+0%29\" Solve by factoring.
\n" ); document.write( "\"%282x-3%29%28x%2B2%29+=0\"
\n" ); document.write( "\"2x-3+=+0\" or \"x%2B2+=+0\" so that...
\n" ); document.write( "\"x+=+3%2F2\" or \"x+=+-2\" Discard the negative solution as lengths are positive.
\n" ); document.write( "\"highlight%28x+=+3%2F2%29\"
\n" ); document.write( "\"PQ+=+5x\"
\n" ); document.write( "\"PQ+=+5%283%2F2%29\"
\n" ); document.write( "\"highlight%28PQ+=+7.5%29\"cm.
\n" ); document.write( "
\n" );
