Hey, to find the area of the rhombus all you have to do is multiple the horizontal part in the inside to the vertical part (also inside the rhombus). After that divide by two and you have your answer.
The minimum happens at x = -b/2a
x = -30 / 2(3) = -30/6 = -5
Now replace x in the equation with -5 and solve:
3(-5)^2 + 30(-5) +27 = 75 - 150 + 27 = -48
The minimum is at (-5,-48)
