Answer:
Height=28
Step-by-step explanation:
You have to work backwards using the formula for a triangle, A=1/2bh
Plug your values in, 126=1/2 9 h
126=4.5 h
126 divided by 4.5 is 28

The exponential function is 
<h3>How to determine the equation?</h3>
An exponential function is represented as:
y = b^x
Where b represents the base.
The base is given as:
b = 12
So, we have:
y = (12)^x
It is vertically compressed by a factor of 1/8.
So, we have:
y = 18(12)^x
When reflected across the y-axis, we have:

The horizontal asymptote is y = 2.
So, we have:

It passes through the point (-3, 4).
So, we shift the function to the right by 4 units

Express as a function

Hence, the exponential function is

Perimeter of rectangle is 8x and Area is 3x^2 + 2x -1..
Lets try to solve out the problem,
Length = 3x-1
Width = x+1
Perimeter = 2(l+b)
Area = l*b
Perimeter= 2 (3x-1 + x+1)
P= 8x
Area = (3x-1) (x+1)
=> 3x(x+1) -1 (x+1)
=> 3x^2 + 3x -x -1
=> 3x^2 + 2x -1.
Hence Perimeter of rectangle is 8x and Area is 3x^2 + 2x -1..
