What is a perimeter? It's the area around. Think of a perimeter fence - that's the amount of fence you need to keep predators out of your land. The formula for perimeter is 2W + 2L (2 pieces of fence for each of the lengths and 2 pieces of fence for each of the widths).
\n" ); document.write( ".
\n" ); document.write( "The problem tells us that the L pieces are (2*W)+5
\n" ); document.write( "It also gives us the total, 34. Now we just need to plug in numbers.
\n" ); document.write( ".
\n" ); document.write( "2W + 2L = 34
\n" ); document.write( "2W + 2(2W+5)= 34 (we just substituted the value for L, given in the problem)
\n" ); document.write( "2W + 4W + 10 = 34 (distributed the 2 on the outside of the brackets)
\n" ); document.write( "Add the Ws:
\n" ); document.write( "6W + 10 = 34
\n" ); document.write( "Subtract 10 from each side:
\n" ); document.write( "6W = 24
\n" ); document.write( "Divide each side by 6:
\n" ); document.write( "W = 4
\n" ); document.write( ".
\n" ); document.write( "If the width is 4, we're told that the length is 5 more than twice the width, or (2*4)+5, which is 13.
\n" ); document.write( ".
\n" ); document.write( "Let's plug the numbers in to make certain.
\n" ); document.write( "2W + 2L = 34
\n" ); document.write( "2(4) + 2(13) = 34
\n" ); document.write( "8 + 26 does indeed equal 34.
\n" ); document.write( "Width = 4; length = 13 \n" ); document.write( "
\n" );
