Question 1 (continued) (f) Karen is making a very special dress from material that is 270 cm long. She has needs to cut this material very carefully into four pieces. The first piece needs to be 30 cm longer than the second piece and the third piece needs to be four times as long as the second piece. The fourth piece of material needs to be half as long as the third piece. How long is the first piece of material?
