This shows a rectangle, with 3 equally separated vertical dotted lines on the left hand side. Each dotted line is separated by 53 cm and there is an arrow from one of these to a question asking: ‘How many of these widths would it take to cover a wall that measures 1440 cm?’. The width of the rectangle is shown as 14.4 metres or 1440 centimetres and the height as 2.34 metres or 234 centimetres.
