the length of a rectangle is twice its width. if the perimeter of the rectangle is 54 m, find its area
\n" ); document.write( "***
\n" ); document.write( "let x=width
\n" ); document.write( "2x=length
\n" ); document.write( "2(length+width)=perimeter
\n" ); document.write( "2(2x+x)=54
\n" ); document.write( "6x=54
\n" ); document.write( "x=9
\n" ); document.write( "2x=18
\n" ); document.write( "area=length*width=9*18=162 sq m \n" ); document.write( "
