A rectangular swimming pool 15 meters by 6 meters will be surrounded by a concrete path 2 meters wide. Find:
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "1. Area of the path\r\n" );
document.write( "----\r\n" );
document.write( "The outside dimensions of the path are 19*10 meters\r\n" );
document.write( "The area inside the path = 19*10 = 190 sq meters\r\n" );
document.write( "Area of the path = 190 - 15*6 = 190 - 90 = 100 sq meters.\r\n" );
document.write( "-----------\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2. The cost of concreting to a depth of 10 cm if the concrete costs $165 per cubic meter\r\n" );
document.write( "If you mean the path:\r\n" );
document.write( "Vol = area*height = 100*0.1 = 10 cubic meters.\r\n" );
document.write( "$165*10 = $1650\r\n" );
