  1. Our l=4*10^4 and b=5*10^5
    A=l*b
    =5*10^5*4*10^4
    =2*10^10 M^2

  2. the area is the product (multiplication) of the two dimensions

    (5 x 10^5 m) * (4 x 10^4 m) = (5 * 4) x (10^5 * 10^4) m^2 = 20 x 10^9 m^2

    for scientific notation the leading digit is between 1 and 10
    ... in this case ... 2 x 10^10 m^2

    area is measured in square meters
