Answer: [tex]2*10^{10}\ m^2[/tex]
Step-by-step explanation:
We need to use the formula for calculate the area of a rectangle. This is:
[tex]A=lw[/tex]
Where "l" is the length and "w" is the width.
In this case, we can say that:
[tex]l=5*10^5\ m\\\\w=4*10^4\ m[/tex]
Therefore, substituting values into the formula, we get that the area of land in square meters is:
[tex]A=(5*10^{5}\ m)(4*10^{4}\ m)\\\\A=2*10^{10}\ m^2[/tex]
