Length = $\"l\"$
\n" ); document.write( "Width = $\"w\"$
\n" ); document.write( " $\"w+=+x\"$
\n" ); document.write( " $\"l+=+3x+-+5\"$
\n" ); document.write( " $\"P+=+2w+%2B+2l\"$
\n" ); document.write( " $\"60+=+2x+%2B+2%283x+-+5%29\"$
\n" ); document.write( " $\"60+=+2x+%2B+6x+-+10\"$
\n" ); document.write( " $\"8x+=+70\"$
\n" ); document.write( " $\"x+=+8.75\"$
\n" ); document.write( " $\"w+=+8.75\"$
\n" ); document.write( " $\"l+=+3x+-+5\"$
\n" ); document.write( " $\"l+=+3%2A8.75+-+5\"$
\n" ); document.write( " $\"l+=+21.25\"$
\n" ); document.write( "Width is 8.75 inches and length is 21.25 inches
\n" ); document.write( "check:
\n" ); document.write( " $\"60+=+2x+%2B+2%283x+-+5%29\"$
\n" ); document.write( " $\"60+=+2%2A8.75+%2B+2%283%2A8.75+-5%29\"$
\n" ); document.write( " $\"60+=+17.5+%2B+2%2826.25+-+5%29\"$
\n" ); document.write( " $\"60+=+17.5+%2B+42.5\"$
\n" ); document.write( " $\"60+=+60\"$
