By inspection I can see it must be a 4' x 9' window, but we solve it by
\n" ); document.write( "L = W + 5
\n" ); document.write( "and
\n" ); document.write( "A = LW = 36
\n" ); document.write( "(W+5)(W) = 36
\n" ); document.write( "W^2 + 5W - 36 = 0
\n" ); document.write( "(W + 9)(W - 4) = 0
\n" ); document.write( "W = 4 feet and then
\n" ); document.write( "L = W + 5 = 9 feet
\n" ); document.write( "
\n" ); document.write( "
\n" );
