    1209.95 km^2

    Step-by-step explanation:

    This can be represented as exponential decreasing function.

    y = a (1 - r) t

    a = starting amount

    r = rate

    t = years

    y = 2500 (1 -.07) ^10

    = 2500 (.93) ^10 = 1209.95

    In 10 years, the forest will shrink in size to 1209.95 km^2
