Algebra.Com's Answer #164085 by MathTherapy(10858) You can put this solution on YOUR website! a rectangular room has a permeter of 48 ft. the width is two-thirds of the length. what are the dimensions of the room?\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let the length of the room be L. Then the width is \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Since perimeter = 48, and perimeter = 2L + 2W, then we'll have: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "6L + 4L = 144 ----- Multiply by LCD, 3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "10L = 144\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Therefore, length of the room, or L = \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "---------- \n" ); document.write( "Check \n" ); document.write( "----------\r \n" ); document.write( "\n" ); document.write( "2L + 2W = 48\r \n" ); document.write( "\n" ); document.write( "2(14.4) + 2(9.6) = 48\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "28.8 + 19.2 = 48 (TRUE) \n" ); document.write( " \n" ); document.write( " |
