PQRS) = area(PQTS) + area(QRT)934323322131332)(=×+×=. Alternatively, as PQ is parallel to SR, PQRS is a trapezium.We now use the fact that the area of a trapezium is its height multiplied by the average length of its parallel sides. Hence, PQRShas area. )1(3121332+×93432332=×=. The tile is made up of three copies of PQRS. So its area is .3334934=×1 1 1 1 1 1
