14 Slot Cars Pip is building model car racing tracks using a large supply of the two types of square plate shown. Ignoring the tabs and slots where plates are snapped together, both types measure 20 cm x 20 cm. In the first type, the track is a straight line joining the middles of opposite sides. In the second, the track is a quarter circle joining the middles of adjacent sides. Plates can be snapped together in any orientation, as long as the track is continuous. 20 cm 20 cm 20 cm Pip wants to complete the track shown below but, because there is lim- ited space, additional plates can only be put in the 4 x 4 grid indicated by dotted lines.
