You can put this solution on YOUR website!
Let the width be \"x\", you have the length is as twice as the width, means the length will be \"2x\"
\n" ); document.write( "Perimeter = (Length + width)*2
\n" ); document.write( "So you have the equation:
\n" ); document.write( " $\"%28x%2B2x%29%2A2+=+30\"$
\n" ); document.write( " $\"%283x%29%2A2+=+30\"$
\n" ); document.write( " $\"6x+=+30\"$
\n" ); document.write( " $\"x+=+5\"$
\n" ); document.write( "So your width is 5 meters
\n" ); document.write( "TA-DAH
\n" ); document.write( ":D \n" ); document.write( "
