Length of pool 25 feet
\n" ); document.write( "Width = 10 feet
\n" ); document.write( "width of side walk=2.5m
\n" ); document.write( "Area = 25 * 10 250 m^2 \r
\n" ); document.write( "\n" ); document.write( "Length with concrete walkway = 25+5=30m
\n" ); document.write( "width with concrete walkway = 10+5=15m
\n" ); document.write( "Area of pool+ walkaway= (10+5)(25+5)
\n" ); document.write( "Area of pool+ walkaway= 450
\n" ); document.write( "Area of walkway = area of (pool+walkway)-areaof garden=
\n" ); document.write( "450 - 250
\n" ); document.write( "Area of walkway= 200 m^2
\n" ); document.write( "
