Programme 17: Six Flat Worms
Finding areas of rectangles

Sad Man has six paper worms that he puts to bed. He wants to know how much material he would need to make a bedspread to cover the worms. Bad Man provides the answer: a rectangle, 10cm x 6cm with an area of 60 square centimetres. In the warm-up session, the contestants have to measure several rectangular objects. Bad Man rearranges their measurements to display the formula: area = length x breadth. Bad Man upsets some people by talking of a PAT tax - a tax for the area of ground they or their pets cover. In the Great Hall, the contestants succeed with the test to estimate then measure some more items. They are pleased to get another maths card.
