Remember that the perimeter is a fence. You'll need two pieces of length and two pieces of width. 2L + 2W = P
\n" ); document.write( "The problem gives you the following:
\n" ); document.write( "P = 22
\n" ); document.write( "L = 2W + 5 (\"length of a certain rectangle is 5 meters more than twice its width\")
\n" ); document.write( ".
\n" ); document.write( "Substitute the value of L into the root equation
\n" ); document.write( "2(2W + 5) + 2W = P
\n" ); document.write( "Distribute
\n" ); document.write( "4W +10 + 2W = 22
\n" ); document.write( "Add the Ws
\n" ); document.write( "6W + 10 = 22
\n" ); document.write( "Subtract 10 from each side
\n" ); document.write( "6W = 12
\n" ); document.write( "Divide each side by 6
\n" ); document.write( "W = 2 <<--
\n" ); document.write( ".
\n" ); document.write( "Let's plug it back into the original question to make certain.
\n" ); document.write( "\"Suppose the length of a certain rectangle is 5 meters more than twice its width [(2*2)+5 = 9] and the perimeter is 22 meters\"
\n" ); document.write( "Then we'd have 2 pieces of 9' and 2 pieces of 2'. 9+9+2+2 = 22
\n" ); document.write( "Success! \n" ); document.write( "
\n" );
