Question

Using the information from the previous question, find the equation in standard form for the area of the fenced-in section in terms of the length of the field.
(area = length • width)

Answer 1

Let's do this together.

Answer 2

the length and width added together would be the answer for the area.

Answer 3

So, what is the length and width added together?

Answer 4

you know area = length • width
length = x - 200
width = x - 300

area = ?

Answer 5

area = (x-200)(x-300) = ?

Answer 6

60000

Answer 7

Correct answer:

y= (x − 200)(x − 300)

= x2 − 300x − 200x + 60,000

= x2 − 500x + 60,000
