You can put this solution on YOUR website!
i like these kind of problems. :)
\n" ); document.write( "so your equation for perimeter is 2L+2W=P
\n" ); document.write( "and you know that the length (L) is 2 more than the width (W) so that equation would look like L=W+2
\n" ); document.write( "and you know that the perimeter is 46
\n" ); document.write( "so then you plug that into the equation
\n" ); document.write( "2(W+2)+2W=46
\n" ); document.write( "the W+2 goes where L would be because that is what l equals.
\n" ); document.write( "so then you would multiply the 2 by the w and the 2 by the 2 to get rid of the parenthesis.
\n" ); document.write( "2*W=2w and 2*2=4
\n" ); document.write( "so then change the equation
\n" ); document.write( "2w+4+2w=46
\n" ); document.write( "subtract the 4 from both sides.
\n" ); document.write( "2w+2w=42
\n" ); document.write( "combine the W's
\n" ); document.write( "4w=42
\n" ); document.write( "divide both sides by 4
\n" ); document.write( "w=10.5
\n" ); document.write( "then you would go back to the original equation and plug in the w=10.5
\n" ); document.write( "2L+2W=46
\n" ); document.write( "2L+2(10.5)=46
\n" ); document.write( "2L+21=46
\n" ); document.write( "subtract the 21 from both sides
\n" ); document.write( "2L=25
\n" ); document.write( "divide both sides by 2
\n" ); document.write( "L=12.5
\n" ); document.write( "and then plug it into the equation to make sure it works.
\n" ); document.write( "2(12.5)+2(10.5)=46
\n" ); document.write( "25+21=46***
\n" ); document.write( "Length is 12.5 meters and Width is 10.5 Meters.
