length of the room = 20 meters.
\n" ); document.write( "width of the room = 18 meters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you want a margin of 1 meter around the carpet.
\n" ); document.write( "you have to subtract 1 meter from both sides of the length of the room to get:
\n" ); document.write( "length of the carpet = 20 - 2 = 18 meters.
\n" ); document.write( "you have to subtract 1 meter from both sides of the width of the room to get:
\n" ); document.write( "width of the carpet = 18 - 2 = 16 meters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "area of the carpet is 18 * 16 = 288 square meters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "at a cost of 150 rupees for each square foot, the total cost would be equal to:
\n" ); document.write( "150 * 288 = 43,200 rupees.\r
\n" ); document.write( "
