Algebra.Com's Answer #504151 by LinnW(1048) You can put this solution on YOUR website! Set W = width, L = length \n" ); document.write( "2W + 2L = perimeter \n" ); document.write( "2W + 2L = 326 for our problem \n" ); document.write( "L = W + 45 \n" ); document.write( "Substitute (W + 45) for L in 2W + 2L = 326 \n" ); document.write( "2W + 2(W + 45) = 326 \n" ); document.write( "2W + 2W + 90 = 326 \n" ); document.write( "4W + 90 = 326 \n" ); document.write( "add -90 to each side \n" ); document.write( "4W = 236 \n" ); document.write( "divide each side by 4 \n" ); document.write( "W = 59 \n" ); document.write( "Since L = W + 45 \n" ); document.write( "L = 59 + 45 = 104 \n" ); document.write( " |
