let l be length and w be width, then
\n" ); document.write( "l = 3w
\n" ); document.write( "Perimeter(P) = 2l + 2w
\n" ); document.write( "400 = 2(3w) + 2w
\n" ); document.write( "400 = 8w
\n" ); document.write( "w = 50
\n" ); document.write( "l = 3*50 = 150
\n" ); document.write( "Area = 50 * 150 = 7500 square feet
\n" ); document.write( "
\n" ); document.write( "
