Answer:
50, 60, 50, and 60
Step-by-step explanation:
xy = 3000
2x + 2y = 220
Rewrite the second equation
y = -x + 110
Substitute this into the first equation.
x(-x + 110) = 3000
-x^2 + 110x - 3000
Divide by -1
x^2 - 110x + 3000
(x - 60) (x - 50)
x = 60, 50
When x = 60, y = 50 and vice versa, so the sides are 50, 60, 50, and 60.
