The mode is two modes 4, and 5 and the description idk how to do sorry bud.
Let the land area of country A = a
and the land area of country B = b
a + b = 199973
a = b + 573
(b + 573) + b = 199973
2b = 199400
b = 99700
a = 100273
The land area of country A is 100,273 square kilometers
and the land area of country B is 99,700 square kilometers.
