You can put this solution on YOUR website!
The equation for the perimeter of a rectangle is : P = 2L + 2W
\n" ); document.write( "You can rewrite that equation to solve for W
\n" ); document.write( "\"P+=+2L+%2B+2W\"
\n" ); document.write( "Subtract 2L from both sides
\n" ); document.write( "\"P+-+2L+=+2W\"
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( "\"%28P+-+2L%29%2F2+=+W\"
\n" ); document.write( "-----------------------------
\n" ); document.write( "Now all you have to do is plug in your given values.
\n" ); document.write( "\"72+-+2%2A%2815%29%29%2F2+=+W\"
\n" ); document.write( "\"%2872+-+30%29%2F2+=+W\"
\n" ); document.write( "\"42+%2F+2+=+W\"
\n" ); document.write( "\"21+=+W\"
\n" ); document.write( "
\n" );
