Algebra.Com's Answer #28834 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Let the perimeter be P. \n" ); document.write( "P = 2L + 2W = 600 \n" ); document.write( "Then L = 2 + 3W \n" ); document.write( "Now substitute and solve for the width, W. \n" ); document.write( "2(2 + 3W) + 2W = 600 \n" ); document.write( "4 + 6W + 2W = 600 \n" ); document.write( "8W + 4 = 600 \n" ); document.write( "8W = 596 \n" ); document.write( "W = 74.5 \n" ); document.write( "L = 2 + 3W = 2 + 3(74.5) = \n" ); document.write( "L = 225.5 \n" ); document.write( " |
