You can put this solution on YOUR website!
The formula for perimeter is:
\n" ); document.write( " $\"+P+=+2L+%2B+2W+\"$
\n" ); document.write( "where
\n" ); document.write( " $\"+L+=+length+\"$
\n" ); document.write( " $\"+W+=+width+\"$
\n" ); document.write( "-----------------
\n" ); document.write( "given:
\n" ); document.write( " $\"+L+=+3W+-+4+\"$
\n" ); document.write( "Plug this into above formula:
\n" ); document.write( " $\"+P+=+2%2A%28+3W+-+4+%29+%2B+2W+\"$
\n" ); document.write( " $\"+P+=+6W+-+8+%2B+2W+\"$
\n" ); document.write( " $\"+P+=+8W+-+8+\"$
\n" ); document.write( "You are given that $\"+P+=+88+\"$ ft
\n" ); document.write( " $\"+88+=+8W+-+8+\"$
\n" ); document.write( "Divide both sides by $\"+8+\"$
\n" ); document.write( " $\"+11+=+W+-+1+\"$
\n" ); document.write( " $\"+W+=+12+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+L+=+3W+-+4+\"$
\n" ); document.write( " $\"+L+=+3%2A12+-+4+\"$
\n" ); document.write( " $\"+L+=+36+-+4+\"$
\n" ); document.write( " $\"+L+=+32+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "The yard is 32 x 12
\n" ); document.write( "-------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+P+=+2L+%2B+2W+\"$
\n" ); document.write( " $\"+P+=+2%2A32+%2B+2%2A12+\"$
\n" ); document.write( " $\"+P+=+64+%2B+24+\"$
\n" ); document.write( " $\"+P+=+88+\"$
\n" ); document.write( "OK\r
