Perimeter = 2(length+breadth) \n" ); document.write( "=2(3x+x+2) \n" ); document.write( "=2(4x+2) \n" ); document.write( "=8x+4 \n" ); document.write( "Since the perimeter is required to be 40yds, \n" ); document.write( "8x+4=40 \n" ); document.write( "8x=36 \n" ); document.write( "x=4.5\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
