Algebra.Com's Answer #600911 by Timnewman(323)![]() ![]() You can put this solution on YOUR website! let the width of the rectngle \n" ); document.write( "be w \n" ); document.write( "lenght L=9w-38 ----(1) \n" ); document.write( "Are of the a rectangle=L*W \n" ); document.write( " therefore, \n" ); document.write( " LW=5992 ---(2) \n" ); document.write( " From (1) \n" ); document.write( " L=9w-38 \n" ); document.write( " w=(L+38)/9 ----(3) \n" ); document.write( "substitute for w in (2) using(3) \n" ); document.write( " L(L+38)/9=5992 \n" ); document.write( "(Lē+38L)/9=5992 \n" ); document.write( "Lē+38L=53928 \n" ); document.write( "then, \n" ); document.write( "Lē+38L-53892=0 \n" ); document.write( "solving the quadratic equation, \n" ); document.write( "L=309.3yerds \n" ); document.write( " |
