Answer:
137 ft²
Step-by-step explanation:
The shop is rectangular in shape. The area of a rectangle is given by:
Area = length * width
Since the length of the shop = 20 ft and the width = 10 ft, therefore:
Area of the shop = length * width = 20 ft * 10 ft = 200 ft²
The part that would not be tiled is of triangular shape. The area of a triangle is given as:
Area = (1/2) * base * height
The base of the triangle = 18 ft, the height = 7 ft. Hence:
Area of non tiled part = (1/2) * base * height = (1/2) * 18 ft * 7 ft = 63 ft²
The total square feet of tile needed to complete the job = Area of shop - Area of non tiled part
The total square feet of tile needed to complete the job = 200 ft² - 63 ft² = 137 ft²

You can find the inverse function for
.. y = (1 +e^x)/(1 -e^x)
by swapping the variables and solving for y.
.. x = (1 +e^y)/(1 -e^y)
.. x(1 -e^y) = 1 +e^y
.. x -1 = e^y*(1 +x)
.. e^y = (x -1)/(x +1)
.. y = ln((x -1)/(x +1)) . . . . . your inverse function

The orange dashed line is there to help you see the inverse function is the original function reflected across the line y=x.
