The length of a rectangle is half the width. The area is 25 square meters. So whats the perimeter?
\n" ); document.write( "***
\n" ); document.write( "let x=length
\n" ); document.write( "2x=width
\n" ); document.write( "length*width=area
\n" ); document.write( "x*2x=25
\n" ); document.write( "2x^2=25
\n" ); document.write( "x^2=25/2
\n" ); document.write( "x=5/√2=5√2/2(length)
\n" ); document.write( "2x=5√2(width)
\n" ); document.write( "2(width+length)=perimeter
\n" ); document.write( "2(5√2+5√2/2)=10√2+5√2=15√2
\n" ); document.write( "perimeter=15√2 meters \n" ); document.write( "
\n" );
