Since the height is different on both ends, we can assume that the wall is a trapezoid. Knowing that, we can replace the measures we know in the formula and our onky variable is the length of the wall - we only need to isolate it.
A= ((b+B)h)/2
26.4=((2+2.4)h)/2
52.8=4.4h
h=12

The profit function is the difference between the cost and revenue functions
The profit function is 
<h3>How to calculate the profit function</h3>
The functions are given as:
- Cost function: C(x) =0.6x + 15000
- Revenue function: R(x) =1.25x
The profit function is then calculated as:

So, we have:

Evaluate the differences

Hence, the profit function is
