Um where the problem or number?
Answer:
The area in factored form is 
.
The area in standard form is 
.
Step-by-step explanation:
The area of a rectangle is length times width.
So the area here is (x+2)(x-5).
They are probably not looking for A=(x+2)(x-5) because it requires too little work.
They probably want A in standard form instead of factored form.
Let's use foil:
First x(x)=x^2
Outer: x(-5)=-5x
Inner: 2(x)=2x
Last: 2(-5)=-10
---------------------Adding together: 
.
The area in factored form is .
The area in standard form is .
(37.5)(12.5)=x(15)
468.75=15x
x=31.25

The number from standard form to decimal form is as follows:
2.077 × 10⁻⁴ = 0.0002077
<h3>How to express number in standard form?</h3>
Standard form is a convenient way of writing very large or very small numbers.
Standard form is a way of writing a number so it is easier to read.
Standard form is like scientific notation and is typically used in science.
Standard form is like scientific notation and it is represented in the format as follows:
a × 10ᵇ
Therefore, the number is already in standard form but we can convert it back to decimal form as follows:
2.077 × 10⁻⁴ = 2.077 × 1 / 10000 = 0.0002077
