    1300 km²

    Step-by-step explanation:

    A = P (1 + r) ^t

    where A is the final amount,

    P is the initial amount,

    r is the rate,

    and t is time.

    Given P = 2600, r = - 0.045, and t = 15.

    A = 2600 (1 - 0.045) ^15

    A = 1303.2

    Rounded, the area decreases to approximately 1300 km².
