Algebra.Com's Answer #584207 by amarjeeth123(570)![]() ![]() ![]() You can put this solution on YOUR website! Let the base of the rectangle be x. \n" ); document.write( "Then the height is (x+6). \n" ); document.write( "Area of the rectangle is 91 cm^2. \n" ); document.write( "x(x+6)=91 \n" ); document.write( "x^2+6x-91=0 \n" ); document.write( "x^2+13x-7x-91=0 \n" ); document.write( "x(x+13)-7(x+13)=0 \n" ); document.write( "(x-7)(x+13)=0 \n" ); document.write( "x=7 is the solution \n" ); document.write( "Height=13 cm \n" ); document.write( "Base=7 cm \n" ); document.write( "Perimeter of the rectangle=2(7+13)=40 cm \n" ); document.write( " |
