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`

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`
