Question:

Solution:

Consider the following diagram:

the area of a rectangle is given by the following formula:

$\text{A =(w)(h)}$

so, to solve this problem we must perform a multiplication:

$A=(5x10^5)(4x10^4\text{)}$

applying the properties of exponents, this is equivalent to:

$A=(5)(4)(10^(5+4))=(5)(4)(10^9\text{)}$

this is equivalent to:

$A=(20)x10^9=20000000000^{}=2x10^(10)$

we can conclude that the correct answer is:

A) to solve this problem we must perform a multiplication.

B) the area of the land is:

$A=2x10^(10)m^2^{}$
