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
