Algebra.Com's Answer #145101 by MathTherapy(10553)![]() ![]() You can put this solution on YOUR website! Let the width of the rectangle be w \n" ); document.write( "Then the length of the rectangle is w + 40\r \n" ); document.write( "\n" ); document.write( "Then, 2w + 2(w + 40) = 220 \n" ); document.write( "2w + 2w + 80 = 220 \n" ); document.write( "4w = 140 \n" ); document.write( "w = 35\r \n" ); document.write( "\n" ); document.write( "Therefore, width = 35, and length = 75 (35 + 40).\r \n" ); document.write( "\n" ); document.write( "Check: \n" ); document.write( "220 (perimeter) = 2(35) + 2(35 + 40) \n" ); document.write( "220 = 70 + 150 (True) \n" ); document.write( " \n" ); document.write( " |
