Okay what’s the question?
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36
Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.
Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x
I am not that really sure but ig its 5
20 x 18 x 5= 1,800
20 times 18 equals 360, then you mutiply 5 and get 1,800
I didn't really know whatnu were asking so i took a guess..sorey if i didn't help
