Step-by-step explanation:
Hope this helps <3
Tell me if you want an explanation.
Exponential model because it's increasing rapidly.
The answer is C: 
Starting with the given formula for the area, A = 1/2hb, the first step is to isolate h by using the multiplicative inverse of b, which is
on both sides of the equation:

The result will be:

The last step is to use the multiplicative inverse of
, which is 2 or
to further isolate the variable <em>h </em>:

The formula for h will be:
which is the option C in your question.
