Which equation below represents the inverse function b(a) , which takes the trapezoid's area as input and returns as output the length of the other base?

Option C is correct answer.

Step-by-step explanation:

The area for the trapezoid is given as :

A=

where B and b are the bases and h is the height.  

The given height is : h=12 B and b =9

Function is :A(b)

This is simplified as A(b)=

A(b)=

Subtracting 54 from both sides we get : A(b)-54=6b

Now divide both sides by 6 we get : Option C or

Therefore, option C is the right answer.
