Let width of rectangle = X feet
\n" ); document.write( "So its length = 2X \r
\n" ); document.write( "\n" ); document.write( "Using the formula (Length*Width) = Area, we get
\n" ); document.write( "2X*X = 450
\n" ); document.write( "i.e. $\"%28+2X%5E2+%29=+%28450+%29\"$
\n" ); document.write( "i.e. $\"%28+X%5E2+%29=%28+450+%29%2F2\"$
\n" ); document.write( "i.e. $\"%28+X%5E2+%29=%28+225+%29\"$
\n" ); document.write( "so $\"X=%28+sqrt%28225%29%29\"$
\n" ); document.write( "OR X = 15\r
\n" ); document.write( "\n" ); document.write( "So the width of rectangle = X = 15 feet
\n" ); document.write( "& its length = 2X = 2*15 = 30 feet \n" ); document.write( "

\n" );
