A) x * y = 1668
B) (x + y) / 2 = 41.375

B) 2x + 2y = 82.75
x = 1668/y

2 * (1668/y) + 2y = 82.75
Multiplying both sides by "y"
3336 + 2y^2 = 82.75y
2y^2  -82.75y + 3336 =0

Used an online quadratic equation calculator
x1 = 20.688 plus 35.214 i
x2 = 20.688 minus 35.214 i
I don't know if I did that correctly.
