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 trapeziums each of equal area. How could he do this?
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?
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.
