8. Byron is planning to build three attached rectangular enclosures for some of the animals on his farm. He bought 100 m of fencing. He
wants to maximize the total area of the enclozures. He determined a
function, A(x), that models the total area in square metres, where x is
the width of each rectangle:
A(x) = -2x2 + 50x
e
х
- 2x + 50
at
