    The general equation for the area of the forest after t years is

    A (t) = 4300 * (.93) ^t

    .93 since 7 percent decrease means 93 percent stays behind. Now plug in t=12

    A (12) = 4300 (.93) ^12=1799.964

    So about 1800Km^2 will be left after 12 years.

    3400 (0.93) ^t

    3400 (0.93) ^15 = 1144.782931 km2
