Answer:
The answer is option D.
80
Step-by-step explanation:
From the question
[tex]height = \frac{constant}{width} [/tex]
Making constant the subject we have
constant = height × width
From the graph
Using point ( 20, 4)
That's
width= 20
length = 4
constant = 20 × 4
= 80
Also using point ( 10 , 8)
constant = 10 × 8
= 80
Since they are the same the value of the constant is 80
Hope this helps you
