LW = 160 sqft
\n" ); document.write( "(2W+4)(W) = 160
\n" ); document.write( " $\"+2W%5E2+%2B+4W+-+160+=+0+\"$
\n" ); document.write( " $\"+2%28W%5E2+%2B+2W+-+80%29+=+0+\"$
\n" ); document.write( " $\"+2%28W-8%29%28W%2B10%29+=+0+\"$
\n" ); document.write( "W = 8 —> L = 2*8+4 = 20\r
\n" ); document.write( "\n" ); document.write( "—
\n" ); document.write( "Ans: Length is 20ft, width is 8ft
\n" ); document.write( "—\r
