\n" ); document.write( " let the side of the lawn be \"x\" meters
\n" ); document.write( "then total length of the side formed by the path and lawn is \"x+%2B+5m\"
\n" ); document.write( "So as per question\r
\n" ); document.write( "\n" ); document.write( "\"%28x%2B5%29%5E2+-+x%5E2+=+200\"\r
\n" ); document.write( "\n" ); document.write( "⇒\"x%5E2+%2B+10x%2B+25+-+x%5E2+=+200\"\r
\n" ); document.write( "\n" ); document.write( "⇒\"+10x+=+200-25\"\r
\n" ); document.write( "\n" ); document.write( "⇒\"+10x+=+175\"\r
\n" ); document.write( "\n" ); document.write( "⇒\"+x+=+175%2F10\"\r
\n" ); document.write( "\n" ); document.write( "⇒\"x+=+17.5m\"\r
\n" ); document.write( "\n" ); document.write( "so, area of the lawn is \"A=%2817.5%29%5E2+=+389.25m%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
