Start with:
\n" ); document.write( "P = 2(L+W) Substitute P = 126, L = 6W
\n" ); document.write( "126 = 2(6W+W) Simplify.
\n" ); document.write( "63 = 7W Divide by 7.
\n" ); document.write( "9 = W and L = 6(9) = 54.
\n" ); document.write( "Area:
\n" ); document.write( "A = L*W
\n" ); document.write( "A = 54*9
\n" ); document.write( "A = 486 sq.ft.
\n" ); document.write( "
\n" );
