               SUBTOPICS: Area of trapezium and general quadrilateral

               1. The trapezium below can be divided into three identical triangles.















                                                                  2
               If the area of the shaded parallelogram is 16 cm , what is the area of the trapezium?
               A. 24 cm  2                         B. 32 cm  2

               C. 48 cm  2                          D.cannot say without knowing the height



               2. The shape of the top surface of a table is a trapezium. Find its area if its parallel
               sides are 1 m and 1.2 m and perpendicular distance between them is 0.8m.


               3. Length of the fence of a trapezium shaped field ABCD is 120 m. If BC = 48 m,
               CD = 17 m and AD = 40 m,find the area of this field. Side AB is perpendicular to the
               parallel sides AD and BC.


               4.The diagonal of a quadrilateral shaped field is 24 m and the perpendiculars
               dropped on it from the remaining opposite vertices are 8 m and 13 m. Find the area
               of the field.













               Answer:
               1. 24 cm  2                                2. 0.88 m .
                                                                    2
               3. 660 m .                                4. 252 m  2
