A manufacturer of packaging is considering the net design shown below and wants to establish how much material will be wasted from an A0 sheet of card (1189mm x 841 mm). The overall dimensions of a rectangular piece of card needed to make each net is 450mm x 400mm. Assume each net will use 70% of each rectangle. (a) Calculate the area of card wasted making each net from the pre-cut rectangle in m2 to two decimal places. [2 marks] (b) If each net uses one rectangular piece of card, what is the maximum number of complete nets that can be made from one A0 sheet of card?
