In the figure, PQRSPQRSPQRS is a trapezium with PQPQPQ parallel to SRSRSR. The diagonals of the trapezium meet at XXX. UUU lies on SPSPSP and TTT lies on RQRQRQ such that UTUTUT is a line segment through XXX parallel to PQPQPQ. The length of PQPQPQ is 12 cm and the length of SRSRSR is 3 cm. What, in centimetres, is the length of UTUTUT? A4.24.24.2B4.54.54.5C4.84.84.8D5.255.255.25E666
