You can put this solution on YOUR website!
Let $\"L\"$ = length in ft
\n" ); document.write( "Let $\"W\"$ = width in ft
\n" ); document.write( "given:
\n" ); document.write( " $\"L%2AW+=+200\"$
\n" ); document.write( " $\"L+=+2W\"$
\n" ); document.write( "By substitution:
\n" ); document.write( " $\"2W%2AW+=+200\"$
\n" ); document.write( " $\"W%5E2+=+100\"$
\n" ); document.write( " $\"W+=+10\"$
\n" ); document.write( "And, since $\"L+=+2W\"$
\n" ); document.write( " $\"L++=+2%2A10\"$
\n" ); document.write( " $\"L+=+20\"$
\n" ); document.write( "The width is 10 ft
\n" ); document.write( "The length is 20 ft
\n" ); document.write( " \n" ); document.write( "
