Algebra.Com's Answer #151000 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! A rectangle is 4 meters longer than it is wide. The area of the rectangle is 252 square meters. Find the length and width of the rectangle. \n" ); document.write( ". \n" ); document.write( "Let w = width of rectangle \n" ); document.write( "then \n" ); document.write( "w+4 = length of rectangle \n" ); document.write( ". \n" ); document.write( "w(w+4) = 252 \n" ); document.write( "w^2+4w = 252 \n" ); document.write( "w^2+4w-252 = 0 \n" ); document.write( "(w-14)(w+18) = 0 \n" ); document.write( "w = {14, -18} \n" ); document.write( "Throw out the negative solution leaving: \n" ); document.write( "w = 14 meters (width) \n" ); document.write( ". \n" ); document.write( "w+4 =14+4 = 18 meters (length) \n" ); document.write( " \n" ); document.write( " |
