Best ResponseYou've already chosen the best response.0a = xy y + 2x = 60 y = 60  2x  a = x(60  2x) a = 60x  2xx  2xx + 60x = 0  the above quadratic equation is in standard form, with a=2, b=60 and c=0  to solve the quadratic equation, by using the quadratic formula, copy and paste this: 2 60 0 into this solver: https://sooeet.com/math/quadraticequationsolver.php  the quadratic has two real roots at:  x = 0 x = 30  the quadratic has a vertex maximum at: ( 15, 450 )  maximum area (a) occurs when x = 15: y = 60  2*15 y = 30 m  answer: x = 15 m y = 30 m max area = 450 sq.m
