Step-by-step explanation:
H is proportionate to L, meaning that they can be represented as a ratio, 
.
If we know that L in the same ratio is 20, we can set these ratio's equal to each other to find H.
.
To find x, we can cross multiply.
So 
, meaning that when 
, 
.

H varies directly as L.
H=KL.
18=K60.
K=18/60=0.3.
H=0.3L
when H=?,L=20. then.
H=0.3×20=6.
