The expected output is a function in the form of A = f(x)

Firstly find y in terms of x
It's slightly not obvious how you'd do so,but just look at the shape carefully
mellow radish
After that you can break down the shape into two rectangles to find the area
livid abyss
The first rectangle would be equal to x * 20 for example
you can also use the fact that you're given a specific perimeter to find what y is equal to
once you isolate that, replace y in the area function by the equation you found
A(x) will then be expressed in terms of x
to make sure you got the right equations, choose a value for x, then according to the function you found using the perimeter, calculate y. Then check if they and the other measures add up to 160. Find the area of the enclosure using the chosen values for x and y. Note down the number you get, and compare it to your result from plugging the same x into A(x)
