Question

A rectangular section of wilderness will set aside a new life refuge 5×105 meters by 4×10^4 meters. Find the area of land in square meters

Answer 1

Answer: $2*10^{10}\ m^2$

Step-by-step explanation:

We need to use the formula for calculate the area of a rectangle. This is:

$A=lw$

Where "l" is the length and "w" is the width.

In this case, we can say that:

$l=5*10^5\ m\\\\w=4*10^4\ m$

Therefore, substituting values into the formula, we get that the area of land in square meters is:

$A=(5*10^{5}\ m)(4*10^{4}\ m)\\\\A=2*10^{10}\ m^2$
