You can put this solution on YOUR website!
A perimeter is a fence. It requires 2 pieces of length and 2 pieces of width. (2L + 2W = P)
\n" ); document.write( "You're given the following information:
\n" ); document.write( "2L + 2W = 24
\n" ); document.write( "L = 3W
\n" ); document.write( ".
\n" ); document.write( "Replace the value of L in the original equation.
\n" ); document.write( "2(3W) + 2W = 24
\n" ); document.write( "Multiply
\n" ); document.write( "6W + 2W = 24
\n" ); document.write( "Add the Ws
\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 you have the width, you can calculate the Length (you were given that length is 3x the width).
\n" ); document.write( "L = 3*3, or 9
\n" ); document.write( ".
\n" ); document.write( "Let's plug those values in to make certain.
\n" ); document.write( "(2*9) + (2*3) = 24
\n" ); document.write( "18 + 6 does indeed equal 24. \n" ); document.write( "

\n" );
