Clue
Draw a labelled diagram of the sports ground. The diagram represents the sports ground. The lawnmower starts at the bottom, cutting strips of a, b, c, d and then starting his second circuit at e. Since it requires 11 + 14 = 25 circuits to cut the entire sports ground and each path is 2 metres wide, then the sports ground is 25 × 2 × 2 = 100 metres wide. Now think about the width and area of the sports ground. |
