---
325 = 2x + y
xy = 11250
---
y = 325 - 2x
x(325 - 2x) = 11250
-2xx + 325x - 11250 = 0
---
the above quadratic equation is in standard form, with a=-2, b=325, and c=-11250
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
-2 325 -11250
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
x = 50
x = 112.5
---
the problem has two solutions:
---
solution 1:
x = 50 m
y = 225 m
---
solution 2:
x = 112.5 m
y = 100 m
