2002 The Eagle Courier Company has a limit on the size of parcels it will deliver. The size of the parcel is calculated by finding the sum of its length and the distance around the parcel, as shown by the dotted line in the diagram. The maximum size of parcel that Eagle Courier Company will deliver has a sum of 210 cm. A particular parcel is twice as long as it is wide and three times as wide as it is thick. By forming an equation or inequation, calculate the largest possible dimensions in centimetres of this parcel, if it is to meet the 210 cm size restriction described above.

2003 At his flat, Josh makes two rectangular gardens. The herb garden is 2 metres longer than it is wide and has an area of 11.25 m 2. The vegetable garden is 3 metres longer than it is wide and has an area of 13.75 m 2. The combined width of both gardens is 5 metres. Find the length and width of each garden. State any equations you need to use. Show all working.

2004 At the Olympic Games 40 years ago, the average number of competitors per sport was 5 times the number of sports played. In 2004 there were 10 more sports than there were 40 years ago. In 2004 the average number of competitors per sport was 3.5 times greater than 40 years ago. At the 2004 Olympic Games there were 10 500 competitors. Write at least ONE equation to model this situation. Use the model to find the number of sports played at the Olympic Games 40 years ago.

Number of sports played 40 years ago = x At the Olympic Games 40 years ago, the average number of competitors per sport was 5 times the number of sports played. the average number of competitors per sport = 5x In 2004 there were 10 more sports than there were 40 years ago. In 2004, there were x + 10 sports In 2004 the average number of competitors per sport was 3.5 times greater than 40 years ago. In 2004 the average number of competitors per sport = 3.5 x (5x) At the 2004 Olympic Games there were 10 500 competitors. Write at least ONE equation to model this situation. Use the model to find the number of sports played at the Olympic Games 40 years ago.

2008 Sheffield school uses two vans to take a group of students on a field trip. If two students moved from van A to van B, then the two vans would have the same number of students in each. If, instead, two students moved from van B to van A, then van B would have half the number of students that were then in van A. Use this information to find the total number of students on the field trip.
