The sum of the areas of the square and the rectangle is 198 cm 2, and the sum of the perimeters is 80cm. Calculate, using an algebraic method, the dimensions of the rectangle. [7] Turn over.

16 Examiner 11. A length of plastic tube has a uniform circular cross-section. The radius of the circular hole in the centre is xcm. The thickness of the plastic is 3cm and the length of the plastic tube is 5xcm. Given that the volume of the plastic used to make the tube is 88π cm 3, find the radius of the circular hole correct to one decimal place. [8]
