Xy = 216
x = 216/y
2x + 2y = 60
2(216/y) + 2y = 60
432 + 2y^2 = 60y
2y^2 - 60y + 432 = 0
y = 18 , y = 12
if y = 12
x = 216/12
x = 18
length = 18
width = 12
Step-by-step explanation:
I need to use the fact that it has exactly one root to find the y part - do I use the quadratic formula on the last bit I have written?
I have x already and z = x+iy
