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
