A farmer has a field which is the shape of a trapezium as illustrated below. To increase his profits he wishes to grow two different crops. To do this he would like to divide the field into two. . . .
A trapezium is divided into four triangles by its diagonals. Suppose the two triangles containing the parallel sides have areas a and b, what is the area of the trapezium?
Can you find the areas of the trapezia in this sequence?
The diagonals of a trapezium divide it into four parts. Can you create a trapezium where three of those parts are equal in area?
A small circle in a square in a big circle in a trapezium. Using the measurements and clue given, find the area of the trapezium.
