Question

I need help on finding operation on how to solve the problem

Answer 1

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^{}`
