Mr Hendricks is preparing to put tiles on the floor of the lounge in their house. The picture below shows the dimension of the floor.
3.1 What shapes can you identify from the diagram above? (2)
3.2 Use calculations to determine the diameter of part B. (3)
3.3 Calculate the total area of the floor. (3)
3.4 Determine the area to be tiled if its only part A that will be tiled.
Use the formula: Area = length x breadth (3)
3.5 If the area of one tile is 30 cm x 30 cm, calculate the number of tiles that would be needed to tile part A. (5)
3.6 There are 10 tiles in one box. Mr Hendricks and his wife claims that they are going to use exactly 18 boxes. Verify, with the necessary calculations, whether the statement is valid or not. (4)
