Picture is x by 3x.
\n" ); document.write( "Picture's area is 3x^2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Border has uniform width, surrounding the picture, 2 cms.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Total area is \"%28x%2B2%2A2%29%283x%2B2%2A2%29\"
\n" ); document.write( "\"%28x%2B4%29%283x%2B4%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "JUST the area of the border is 200 SQUARE CENTIMETERS.
\n" ); document.write( "JUST the area of the border is \"highlight_green%28%28x%2B4%29%283x%2B4%29-3x%5E2=200%29\".
\n" ); document.write( "Simplify and solve this equation. You will have x from which to evaluate 3x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Steps from there:
\n" ); document.write( "\"3x%5E2%2B12x%2B4x%2B16-3x%5E2=200\"
\n" ); document.write( "\"16x%2B16=200\"
\n" ); document.write( "\"16x=184\"
\n" ); document.write( "\"2x=23\"
\n" ); document.write( "\"highlight%28x=23%2F2%29\", and you can find 3x from this.
\n" ); document.write( "
\n" );
