A new car manufacturer is designing a logo. It is in the shape of a diamond inside a rectangle. The diamond is to have a horizontal width of 3 cm and an area equal to one sixth of the area of the rectangle. Find the required height of the diamond.
If the diamond is just a rotated square, then its diagonal is 3, so its area is 9/2.
So, the rectangle has width 3 and area 27, so its height is 9.
