the length of a rectangle is 5cm longer than its width the area is 66 cm square find the perimeter of this rectangle
\n" ); document.write( "***
\n" ); document.write( "let x=width of rectangle
\n" ); document.write( "x+5=length of rectangle
\n" ); document.write( "length*width=area
\n" ); document.write( "x(x+5)=66
\n" ); document.write( "x^2+5x-66=0
\n" ); document.write( "(x+11)(x-6)=0
\n" ); document.write( "x=6
\n" ); document.write( "x+5=11
\n" ); document.write( "width of rectangle=6
\n" ); document.write( "length of rectangle=11
\n" ); document.write( "2*(width+length)=perimeter
\n" ); document.write( "2(6+11)=34
\n" ); document.write( "perimeter of rectangle=34 cm \n" ); document.write( "
\n" );
