Look at the room carefully, the length of the room is 13 feet\r
\n" ); document.write( "\n" ); document.write( "And the width = 11feet\r
\n" ); document.write( "\n" ); document.write( "Heigth = 10feet\r
\n" ); document.write( "\n" ); document.write( "The area of the one side of the room = 2( 13 * 10) = 160 feet\r
\n" ); document.write( "\n" ); document.write( "The area of the another side of the room is = 2(11*10 ) = 220feet\r
\n" ); document.write( "\n" ); document.write( "Therefore the total roll area = 220 + 160 = 380feet\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since one roll is 2.5 * 50 = 125 feet\r
\n" ); document.write( "\n" ); document.write( "Therefore \"x\" number of rolls = 380 rolls\r
\n" ); document.write( "\n" ); document.write( " = 380 / 125 = 3.04 rolls\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore we require 3.04 rolls to cover a rectangular room on all four sides. \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
