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

Hey there! I'm happy to help!
First, let's see how many 11/18 miles fit into 11 miles.
11÷11/18=18
Therefore, they will need to 18 repeats of this 11/18, and since they move 11/18 mile per hour, this means that it would take 18 hours for the spider to go 11 miles.
Have a wonderful day! :D
