Dylan makes cupboards using wood. One of his cupboard designs is made from:
3 small panels 550 mm by 550 mm
4 large panels 2150 mm by 550 mm.

The boards used to cut the panels are 2500 mm by 2000
mm. There must be no joins in the panels.

Dylan has an order for 6 of these cupboards. He buys 9
boards to cut the panels.

Has Dylan bought enough wooden boards?
