Heya....  Here is ur answer....   Let the unit of length be 1L.  Initial, value of 1L = k(say)  Then,  side of square be 'a'k units.  Area of square = ( a^2) k^2 units.  = a^2 L^2 units     Now,   Unit of length is tripled, 1L = 3k units.  => 1k = L/3 .  Then,   Area of square is a^2 k^2 units.  => a^2 (L/3)^2 => a^2L^2/9 units.    There fore, Numerical value of area of square becomes 1/9 of initial in original units.   Tysm.....@gozmit
