A cylinder has surface area of 402 cm2. The height is three times greater than the radius. What is the height of the cylinder?

Areas/Rectangle
2x-1

Areas/Rectangle
x^2-1 would it be this?

Areas/Rectangle
Sorry the width is x+5, I think I combine the like terms, is that right?

Areas/Rectangle
Given that the area of the rectangle is 2x^2 + 9x - 5 , determine the length of the rectangle.
