The best and most correct answer among the choices provided by your question is the second choice or letter B "20".
The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000
14000=(120+x)(80+x)
14000=9600+200x+x^2
x^2+200x-4400=0
x^2-20x+220x-4400=0
x(x-20)+220(x-20)=0
(x+220)(x-20)=0, since x is an increase it must be greater than zero so
x=20ft
(120+20)(80+20)=14000ft^2

Answer:
409
Step-by-step explanation:
18 x
--- = ---
22 500
18 x 500 = 9000
9000/22 = 409
Let's name the x-coordinates and y-coordinates
- x-coordinate = abscicca
- y-coordinate = ordinate
So, According to question
- Abscicca of Point D = Ordinate of Point B
- Ordinate of Point D = Abscicca of Point A
Abscicca of Point A = 2
Ordinate of Point B = -4
<h3>Thus, </h3>
Point D = (-4,2)
