(2.02-2.05)/2.05 = -0.014634 or ~1.46% smaller

The difference is 0.03 million square miles, which is 0.03x1000000 square miles=30000 square miles.

% diff = (new_value - old_value)/old_value * 100 %

new_value = 2.02 Million mi^2
old_value = 2.05 Million mi^2

% diff = (new_value - old_value)/old_value * 100 %

% diff = (2.02 M - 2.05 M)/2.05 M * 100 % = -0.0146 * 100 % = -1.46%

( "-" indicates that it reduced, which makes sense, because 2.02 is smaller than 2.05)
