Think of a perimeter as a fence. How much fencing will you need to build a \"perimeter fence\" around your land?
\n" ); document.write( "You'll need 2 pieces of length and 2 pieces for the width.
\n" ); document.write( "2L + 2W = 26
\n" ); document.write( "The problem tells us that L = 3W + 1
\n" ); document.write( "Let's plug in that value for L.
\n" ); document.write( "2(3W + 1) + 2W = 26
\n" ); document.write( "Distribute the 2:
\n" ); document.write( "6W + 2 + 2W = 26
\n" ); document.write( "Add the Ws together:
\n" ); document.write( "8W + 2 = 26
\n" ); document.write( "Subtract 2 from each side:
\n" ); document.write( "8W = 24
\n" ); document.write( "Divide each side by 8:
\n" ); document.write( "W = 3
\n" ); document.write( ".
\n" ); document.write( "Now that we know the width is 3, what is the length?
\n" ); document.write( "\"1 more than 3x the width\" -- (3x3) +1, or 9+1, or 10
\n" ); document.write( "W = 3; L = 10.
\n" ); document.write( "Let's check the answer.
\n" ); document.write( "2 pieces of width (2*3=6) and 2 pieces for the length (2*10=20).
\n" ); document.write( "6 + 20 = 26.
\n" ); document.write( "It works :-) \n" ); document.write( "
\n" );
