  1. area is length * width, so
    5x10^5 * 4x10^4
    multiplication is commutative, so that's
    5*4 * 10^5*10^4
    = 20 * 10^9
    = 2*10^10 m^2

    if the powers stuff is confusing, it's just shorthand for multiplication
    10^5*10^4 = (10*10*10*10*10)*(10*10*10*10) = 10^9
    just as multiplication is shorthand for addition
    5*4 = 5+5+5+5
