Start with $\"P+=+2%28L%2BW%29\"$ , $\"P+=+70\"$ L = length and W = width.
\n" ); document.write( "1) Length-to-width ratio.3 to 4.
\n" ); document.write( " $\"70+=+2%283x%2B4x%29\"$
\n" ); document.write( " $\"70+=+2%287x%29\"$ Divide both sides by 2.
\n" ); document.write( " $\"35+=+7x\"$ Divide both sides by 7.
\n" ); document.write( " $\"5+=+x\"$ then...
\n" ); document.write( " $\"L+=+3x\"$
\n" ); document.write( " $\"highlight%28L+=+15%29\"$ feet.
\n" ); document.write( " $\"W+=+4x\"$
\n" ); document.write( " $\"highlight%28W+=+20%29\"$ feet.
\n" ); document.write( "Try this on the other two problems. \n" ); document.write( "
